No. Having an extra chromosome is actually a genetic defect. With twins, let's assume they are identical twins, the mother has one egg cell in the fallopian tube ready to be fertilized by a sperm cell. The sperm cell fertilizes the egg cell, but that egg cell then undergoes mitosis. All of the cell contents are duplicated and the cell divides into two. You now have 2 cells with the exact DNA which are twins. In the case of fraternal twins, the mother had two separate ova in her fallopian tubes and both were fertilized by two different sperm cells.
About 1 in 5 million
If they are born from a single pregnancy they are called quadruplets.
The word used for 4 babies born at the same time from the same womb is 'quadruplets'.
NOTE: Before you complete any of these steps, your Sim must already be pregnant.
When in labor your female will now give birth to twins.
yea we twins
No, you have just as much chance as if you period was early or on time.
You have a greater chance if the mother has twins in her family, but only fraternal twins as identical twins are more of a mutation. A woman needs to inherit the gene for multiple ovulation. Even if the man is a twin himself, his sperm can't make a woman release two eggs.
Fertility treatments are the only way to increase your chances besides luck and hereditary.
Very interesting article. It explains the two different ways a twin can be absorbed and disappear. http://www.babyzone.com/features/content/display.asp?TopicID=40&ContentID=1525&Page=1 (Exact Quote) Vanishing Twin Syndrome By Deborah Bohn The rise in early-term ultrasounds has brought the Vanishing Twin Syndrome to light, revealing that a surprising number of twin pregnancies result in the birth of only one baby. �We won the conception lottery!� That�s what I wrote in my online journal when I found out that my husband and I were expecting twins. After months of hormone injections, blood tests, ultrasounds, pills, ovulation test kits and egg extraction procedures, plus a heartbreaking miscarriage, we had finally hit the baby jackpot with the help of a fertility specialist and in vitro fertilization. The ultrasound image at my eight-week check-up showed two shrimp-like embryos and two little heartbeats flashing on the screen. My gynecologist gave me the phone number for a twins support group and told me to get ready for a wild ride! Imagine my shock and horror when the next ultrasound, a mere two weeks later, showed one fat, wriggly embryo and one tiny bean-shaped one with no heartbeat. We were devastated. Grief stricken. How could this have happened? What went wrong? And what was going to happen to the surviving fetus? The doctor said I was experiencing Vanishing Twin Syndrome, a common occurrence in the early stages of a multiple pregnancy. I might feel some cramping and possibly a tiny bit of bleeding, but the healthy baby would most likely survive and the �little one,� as we called it, would be reabsorbed by my body over time and simply�vanish. He was right. Although we were emotionally devastated by the loss of our tiny unborn baby, there was no discomfort or bleeding. My 20-week ultrasound revealed a healthy fetus and an empty amniotic sac, but no sign of the little twin. Our daughter was delivered healthy and on time, but we still think about what it would have been like to raise twins. We still sometimes miss the baby that came and went like a little ghost. Freak of Nature? As strange as it sounds, vanishing twins are pretty common. Before the advent of early ultrasounds, women didn�t realize they were carrying multiple babies until the heartbeats could be heard at 12 weeks or until their regular five-month ultrasound. If two embryos had been conceived and one lost during the first trimester, a mother would never have known it. Experts currently estimate that one-eighth of pregnancies begin as twins. But of course, the percentage of pregnancies that make it to term is smaller. Fertility specialist Dr. Carolyn Givens of the Pacific Fertility Center estimates that between 15 and 20 percent of all twin pregnancies will miscarry one fetus. �That�s what happens what happens with a vanishing twin,� she says, �You have an early miscarriage of the twin.� Those estimates are supported by a 1986 sonogram study of 1,000 pregnancies. Exactly 21.9% of the women carrying twins in the first trimester experienced a �vanishing twin" event. Due to the increased use of fertility drugs and assisted fertility techniques like in vitro fertilization, there�s been a spike in multiple pregnancies and an accompanying rise in early gestation ultrasounds, so what used to be an almost unheard of phenomenon is rapidly becoming a hot topic among mothers. What Happens? When our twin disappeared, I found myself wondering if I�d done something wrong to cause the embryo to die. Did I sleep in the wrong side? Inhale someone�s second-hand smoke? Lug my heavy one-year-old daughter around too much? The fact is that most of the time a twin vanishes during the first trimester for the same reason a single baby miscarries: There�s a fatal genetic problem with the embryo and it couldn�t continue developing into a full-fledged fetus. Dr. Givens explains, �This usually happens within the first eight weeks because that�s when the organs form, and if there�s a problem, this is when it will occur. If there�s a chromosomal problem, some important gene doesn�t turn on or do what it�s supposed to do and the heart will stop developing.� However, older mothers tend to experience vanishing twin losses more frequently. �Spontaneous fraternal twins are more common in older moms because they ovulate more than one egg more often. And older women have a higher rate of miscarriage because of chromosomal abnormalities,� Givens says. Unlike the miscarriage of a singleton, a woman is less likely to have bleeding with a vanishing twin because the healthy embryo keeps generating hormones to keep the placental lining in place for nourishment and protection. That�s why many women have no idea the second twin even existed. There were no obvious signs that it was ever there and no physical indications of a problem when it died. While there is �minimum physical risk to the mother if it happens in the first trimester,� according to Dr. Givens, there is a small (less than 10%) chance that the healthy baby will be lost at the same time. In that event, both embryos would be washed away in the blood of what appears to be a heavy period, but is actually an early stage miscarriage. Late-Term Loss Tragically, just like some singleton babies are lost in the second or even third trimesters, the same goes for twins. But the risks to the mother and surviving baby are much greater in the case of a multiple pregnancy. When a single baby stops growing, the body either expels the fetus, resulting in a miscarriage or a stillborn baby, or a doctor removes the tissue for the safety of the mother. But when a twin is lost late in a pregnancy a few different things can happen. �If you lose a twin after 20 weeks, you are at a much higher risk to lose the other one. There�s so much tissue present that the body wants to expel it and take the live one with it,� Dr Givens explains, �The major risk to losing a twin when the other isn�t ready to be delivered, is the prematurity of the surviving twin.� On the other hand, if non-living tissue remains in the uterus, the mother is at risk for coagulation problems caused by proteins from the tissue releasing into the mother�s bloodstream. This can cause a condition called Disseminated Intravascular Coagulation that can kill the mother and always results in the death of the remaining baby. In extremely rare cases, a late-term twin actually vanishes too. Sometimes the water from the dead fetus is reabsorbed into the mother�s body, but the weight of the surviving twin compresses the remaining fetal tissue and forms a fetus papyraceus�a flattened and "mummified" fetus that can block the vaginal opening and require a cesarean delivery. Occasionally the tissue from the perished twin is absorbed by the surviving fetus and forms a tumor, called a teratoma, filled with its missing sibling�s bone, teeth or hair. There have been cases in which part of a twin projects from the body of the surviving twin, sometimes resulting in extra limbs or other duplicated body parts like organs or bones, only discovered later in life by an x-ray or CAT scan. Stranger than Fiction In extremely rare cases of vanishing twin syndrome, two early stage embryos fuse into a single embryo containing two unique sets of DNA. The surviving twin becomes what�s known as a chimera�essentially two people in one body. Chimeras can have different sets of DNA in different body parts. For instance a male chimera can have one type of DNA in his skin cells but what appears to be an entirely different person�s DNA in his sperm cells. A 2003 study in the New England Journal of Medicine by Dr Margot Kruskall of the Beth Israel Deaconess Medical Center in Boston, Massachusetts, reported the case of a mother who required a kidney transplant. All three of her natural sons were tested as potential donors, but only one appeared to be her biological son, although she gave birth to all of them. Genetic tests revealed that the patient was a chimera�a physical blend of fraternal twin sisters�and her ovaries produced eggs belonging to both twins, thus she could give birth to three sons who were genetic half-brothers; one of them sharing DNA with his mother and two sons sharing DNA with their vanished �aunt.� According to the November 2003 New Scientist magazine, �Some chimeras do have unusual physical features. For example, one girl was discovered to be a chimera because her eyes were different colors, one brown, the other hazel. Others have come to light when doctors investigated problems with their reproductive systems, and found that they had structures from both male and female reproductive organs as a result of having cells of both sexes in their bodies. But most probably go through life utterly unaware of their unusual constitution.� The Emotional Toll In my experience�and everyone�s is different�Vanishing Twin Syndrome is like simultaneously hosting a birthday party and a funeral in the same room. You�re thrilled and relieved that you�ve got a healthy baby growing bigger and stronger, while you�re mortified that you�re carrying a dead baby in your belly and heartbroken by the loss of a child you longed for so desperately. As a fertility specialist, Dr. Givens sees a large number of initial multiple pregnancies that ultimately result in a single live birth. She says, �Prospective parents generally have mixed feelings when they lose a twin. In the fertility world, a lot of times people don�t have kids, this is their first pregnancy, and the loss is almost universally a sad thing for them. But it depends on whether they really wanted twins to begin with. Sometimes couples are a little relieved if they already have children and don�t want twins. Either way we tell them that the twin wasn�t healthy, so the loss was actually a positive thing, although it might not feel that way at the time.� Could You Be a Twin? Could you be the surviving half of a twin pregnancy? Could you have been pregnant with twins and not known it? As reported by Lawrence Wright in The New Yorker, Professor Charles E. Boklage, a developmental biologist at the East Carolina University School of Medicine and a well-known twinning expert says that Vanishing Twin Syndrome �is much too common to be considered phenomenal, and it occurs for too many reasons to be considered any kind of syndrome.� He contends that since most pregnancies fail in the early weeks�often unbeknownst to the mother�the early loss or disappearance of a twin is to be expected. Dr. Boklage estimates that for every set of live twins there are at least six singletons who are survivors of twin conceptions. He says, "Somewhere in the vicinity of ten to fifteen percent of us�and that's a minimum estimate�are walking around thinking we're singletons when in fact we're only the big half!" ----------------------- I'm adding this content September 11, 2009
I am an absorbed twin. I'm 52 years old as of this writing in 2009 and I did not discover the fact of my birth condition until I was in my forties. While I was growing up I had two sets of most of my baby teeth, and I've had three sets of adult molars; they matured and decayed and replaced themselves. I was also born with ovaries and testes, vagina and penis, have feminine skin and hair, masculine skeletal structure, and a capacity to multi-task between the female and male perspectives. I believed myself to be a girl until I started puberty, then accepted that I was a boy until I was in my mid-thirties, and then re-identified as a woman. By the way, the differences between the female and male perspectives are astoundingly different, and I see life from both when I want to.
I have younger twin sisters. I fathered 4 sets of twins, none of whom went full term. And the two sons we created are healthy and well adjusted, and have families of their own.
My genetic profile is all over the place; so much so that the last testing facility has yet to release my profile to me because they can not figure it out. I've been three times by them. It's the VA, and they are not all that up-to-date when it comes to medicine "outside the box". In fact, when I seek health care as a woman they tell me I cannot have certain things because one doctor things I am male, yet they deny other things I need to support male health because I am a woman. Go figure!
So, here you have an open and sincere account of an abosrbed twin life.
Myomectomy alone wouldn't change the likelihood of conceiving twins.
the mccann twins are the related to madeleine mccan who famously went missing
while on holiday with her perants. i cant remember where! i hope this helped XD
Mirror image twins are identical and have mirror image differences but are genetically identical which means they have the same DNA.
A set of mirror-image twins will have similarities like a mole. One twin would have it on his left arm while the other would have it on his right. Another common feature is one twin being left handed, while the other is right handed. For male twins, the swirl of hair crown is often in the opposite direction.
Depends on were the twins are joined at, like the organs, but yes they could.
There is a reference to the Tishman twins in an old folk song, "Shake Hands With Your Uncle Max" by Allan Sherman. It goes: Shake hands with your Uncle Max, my boy
And here is your sister Shirl
And here is your cousin Isabel
That's Irving's oldest girl
And you remember the Tishman twins
Gerald and Jerome
We all came out to greet you
And to wish you welcome home Although there maybe some twin siblings named Tishman somewhere in the world, Gerald and Jerome appear to be fictional.
Not sure what you mean since this is a procedure to abort or clean out the uterus after a miscarriage.
i am a twin and we're not sure if we are identical or fraternal because you can only tell by blood tests for sure but we look very alike and so we are confused a lot so if you are a soon to be parent of twins or something here is what annoys them.
1.the most annoying thing is when people assume you have the same personality because you look alike
2 the second most annoying thing is when people call you ''the twins'' its like ''dude seriously I'm not a label i have a name!!!'' its kinda of like labeling someone by their race or something like ''the native American guy'' or '' the white guy'' and it shows about not having individuality seriously people have names and we want to be called by them
3when people make you share everything. i had a really annoying teacher who was giving every body brownies and my sister didn't raise her hand but changed her mind after afew seconds and the wicked witch of the west split my brownie and was like ''your twins duh'' and first of all just because we are twins doesn't mean we shair every thing and she's not a twin how would she know?
4when people ask stupid questions like''were you Siamese twins''(actuley they are formed when the egg splits when it wasn't supposed to so single birth people are more likely to have become conjoined because our egg was meant to split and their egg was not but it could have) its like ''no you would have seen that on the news when we were born'' or ''have you dated Zach and Cody'' and I'm like 'I'm 12 there like teenagers and you would have seen it on like j-14 and how the heck would we know them and twins don't have to date twins i mean have you scene or know a couple that are bothe twins. but the most annoying queshtion is can you read eachothers thoughts ''oh yeah as we speak I'm reading her thoughts'' duh! no and when people pinch us to see if we can ''feel eachothers pain'' what imbisul tought you that?
5HOLLY WOOD STERIOTYPES here are some holly wood steriotypes you should not follow1 we don't talk at the same time2 we don't dress alike3 we don't have the same personalities4 one of us is not the braver one or the smarter one we're like all siblings better at some things and our other sibling is better in others5the girls are blond6we are spoiled and bratty when people put that on t.v i began cussing them out cause we're not people make us shaire evorey thing! we're the last people on earth to get spoiled because people don't let us have things to our selves
6 when people say fraternal twins don't look alike and identical twins do actulley the difference is that when identical twins are made the egg splits so yes they look alike but fraternal twins started with 2 eggs so they don't allways look alike
7when you make enemies with one twin and began to hate the other before you Even know them cause they look alike when they might be a completely different person.
8and last when people stop to tell us apart witch actually doesn't bother me and some times makes me feel special but when people began gathering around and competing and betting on witch is witch and giving each other money is just so annoying its like GOD didn't put us on earth to entertain you people
9 when people think your not ''real'' twins if you don't have the same names or look the same
10 when people ask if there seeing double. because its random by random strangers and happens all the time. also the answer is obvious NO DUH
11 i am a vegetarian and when my sister use to ba a bipedal carnivore and ate meat when i said''I'm a vegetarian i cant eath that'' people would think she was and not give her meat
Quintuplets. 2-twins 3-triplets 4-quadruplets 5-quintuplets 6-sextuplets 7-septuplets
Since all other Muliti-Birth names are with Greek prefixes, it should be hendectuplets.
Yes you can, although it's very rare. Sometimes two (or more) eggs can be dropped during a single ovulation. So it's possible that if you sleep with two men during your ovulation time then both of their sperm could 'catch an egg', and produce twins with different fathers.
I believe that the double egg-drop happens more commonly with fertility treatment or if the mother is older.
Twins are common in many animal species, such as cats, sheep, ferrets and deer. The incidence of twinning among cattle is about 1-4%, and research is under way to improve the odds of twinning, which can be more profitable for the breeder if complications can be sidestepped or managed. The nine-banded armadillo (Dasypus novemcinctus) has identical twins (usually four babies) as its regular reproduction and not as exceptional cases.

I hope this can help you.
There are two types of twins. Fraternal twins are produced when two eggs are released and two separate sperm fertilize them. These twins are not identical, although they may still look alike because they are siblings.
Identical twins are produced when one egg is fertilized by one sperm. During the zygote stage, the egg splits into two. This creates two separate embryos and thus the children will be identical copies of each other. The same exact chromosome match.
There are two primary types of twins, Identical and Fraternal.
Identical twins occur when the egg splits after fertilization. To date no indication of a genetic link has been found. Anyone has a chance, though small, of having identical twins.
Fraternal twins occur when more than one egg is dropped during ovulation. This trait can be inherited from the mother's side of the family. Studies have shown that the chances are also increased by being overweight or older.
If you want twins you either have to have to magic seeds at the same time and do them at the same time or plant to seeds on the same day and get on their everyday and you will have twins in know time!
You can but you shouldn't an a lot of tattoo artists won't give you one. This is because the huge amount of adrenaline your body produces can cause miscarriage you are also very prone to get a blood infection no matter how clean your tattoo parlour is. Getting a tattoo at any time runs the risk of you contracting diseases such as HIV and Hepatitis. Contracting these, especially while pregnant, can lead to your unborn child contracting them as well. During pregnancy your skin stretches and you tend to bloat, which can change the way the tattoo will look after pregnancy. Your hormones may cause the colors not to take well so you end up unhappy with the resulting color.

You can pretend to be one another and somewhat swap lives now and then ;)
