What are the disadvantages of being an identical twin?
There are quite a few disadvantages. For example people might think you are the same person as your twin and get mixed up. Also people might expect you to act the same as your twin, or / and wear the same clothes. Also people might stare at you in the street if you are with your twin.

The same as anyone else. No genetic marker has been found yet related to identical twins.
Nope.. Research has shown that DNA in twins is different, especially in copy number varitations, which refers to when a gene exists in multiple copies, or a set of letters in the DNA is actually missing. These variations are suspected to lead to increased defense against some infections, or vulnera…bility to others.. http://www.nytimes.com/2008/03/11/health/11real.html . Their genes are very similar. Because the two embryos are the result of a single egg/sperm combination, they have the same genetic origins. They have the same DNA. however, they don't have the same finger prints. Almost! While the sequence begins identical, epigenetics (environmental type factors) appear to cause them to change over time. ( Full Answer )
Luck. There is no way of making someone have identical twins. 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 ident…ical 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. Fertility drugs also make this more likely to happen. ( Full Answer )
Whenever the zygoat (fertilized egg) starts mitosis (cell division) it creates two zygoats. These two zygoats are exactly the same in looks and DNA.

So they might have been born identical, but as they grow up they have different diets, take different amounts of exersize, and live in different environment…s (pollution could affect their health).

Yep. It can only happen in girls, though - and it's very rare. See: http://m.theglobeandmail.com/life/parenting/why-identical-twins-can-look-different/article4186733/?service=mobile and http://www.psychologytoday.com/blog/twofold/200902/why-some-identical-female-twins-are-different
you wont know until the very end what you actually have the babies Answer: Your Sonographer will be able to tell you. I think it is based on how many sacs/ placenta's there are. If there are two they are not identical because they are from two separate eggs.
Non identical twins are produced when the mothers egg and fathers sperm join together to fertilise as usual to form a zygote but the zygote soon starts to divide into two separate cells but the cells both carry the same genes.
Identical twins do not have identical fingerprints.. Identical twins (also known as monozygotic twins) are formed when a single fertilised egg splits in two after conception. As they are from a single zygote, the two individuals share the same genetic makeup, meaning that their DNA is practically …indistinguishable. However, a fingerprint is not entirely dependent on genetics. Along with other physical characteristics, the outcome is determined by the interaction of the individual's genes and the environment as it develops in the uterus. The ultimate shape of the fingerprints is believed to be influenced by there environmental factors, such as blood pressure, nutrition, position in the womb and growth rate of the fingers at the end of first trimester. Therefore, you will find similar patterns of whorls and ridges in the fingerprints of identical twins, but there will also be differences, just like there are differences between the fingerprints on any individual's hands. No, because fingerprints are formed randomly when a baby touchesthe inside of the womb. Fingerprints are unique to each and everyperson. . No, they do not. ( Full Answer )
I believe that DNA is never identical even when twins are born. Everyone is unique and no two souls or fingerprints are identical.
No they do not. Identical twins have identical DNA structure, and therefore they have very similar cell structure, leading them to have vastly similar organs (same size, health issues, etc.). However, everyone, even identical twins, do not share the exact same organs. Some identical twins get migrai…nes, while the other doesn't. In some cases, one twin will be homosexual and the other heterosexual. In any case, by nature, identical twins do not have identical brains, and by nurture they experience different things, learn different things, and process information in different ways, resulting in the twins having differing opinions, etc. No two brains are exactly alike.

Identicals are exactly the same non identicals are just regular twins that are not nessecarily similar.
Identical twins are formed when one fertilized eggs splits. Non-identical twins are formed when two separate eggs are fertilized.
Children are the results of a mix of their parent's DNA. They do not have the exact same DNA, they have half their mother's and half their father's. Character and personality play a major part in allowing anyone to identify a person - particularly parents, who spend a lot of time with, and have …a lot of opportunity to observe the differences between, their children.

The sperm was absorbed by the egg then after the egg split into 2yet still carry same DNA
Identical Twins Sometimes, after fertilisation, the fertilised ovum splits and divides into two balls of cells. Twins formed in this way are identical. They develop from the same ovum. Non-identical Twins Sometimes a woman's ovaries release two or more ova at the same time. If they all be…come fertilised, they all develop into babies. Twins formed in this way are non-identical. They develop from different ova fertilised by different sperms. ( Full Answer )
Identical twins are identical because they both came from the same egg. The term "Identical" is used as they look very much like each other and anybody can say that they are twins by just looking at them.
Sure, but they don't have to. The probability of twin births are somewhat related to ethnicity, but is heavily influenced by random factors.
HA HA HA!!!!!!!!!! They were identical can't you tell? They looked exactly the same!\n. \n---\nThey also looked the same when they collapsed. But the building plans show that they had the same type of material while being made. The North Tower had a TV antenna, so just think of it as a new hair sty…le. ( Full Answer )
No, the Roloff twins (Jeremy and Zachary) are not identical. As the Roloff's point out, Jeremy is average height, and Zach is a little person.
identical twins came from the same fertilized egg that split while fraternal twins came from 2 different fertilized eggs.
There are two two kinds of twins. Gametic twins - two sperms fuse with two eggs to form gametic twins. In the case of gametic twins, the twins are not identical and infact there is a chance for one male and another female. Zygotic twins - zygote forms after fertilisation (Fusion of sperm and egg…). The zygote divides in to two cell and these two new cells develops in to twins. In the case of zygotic twins, the babies are identical and both the twins will be males or females. ( Full Answer )
Identical twins are formed when an egg fertilised by a sperm splits in half to form two different embryos.
Monozygotic (Identical or Maternal) twins are identical because they came from the same egg and were split after conception but before fetal development. Identical twins have nearly identical DNA, however, environmental factors may switch genes on and off, differences are more pronounced as the twin…s age. Dizygotic (Fraternal) twins are not identical. They are as different as any other siblings. ( Full Answer )
When an egg is fertilized by a sperm, it becomes a zygote. That zygote goes through cell division to become an embryo. Sometimes, the zygote splits and becomes two separate organisms - they will be identical twins. If the zygote splits and separates multiple times, you can get triplets or even quad…ruplets. They will all be (more-or-less) genetically identical. If two eggs are released during ovulation and each one is fertilized (by a separate sperm) then you will have fraternal (non-identical) twins. Again, if multiple eggs are released (for example, when a woman is undergoing fertility treatments) and each one is fertilized by a separate sperm, you can get triplets, quadruplets, etc. They will all be genetically different and can even be different sexes.

No, they are ferternal. They have different colored eyes and one used to be shorter then the other. If you get any of their old movies you can tell. Mary-Kate usually has shorter hair then ashley, but that doesn't make them ferternal.
To be strict, if you look real close, they haven't. But their genes are very, very similar. And the why is because identical twins start out as one fertilized egg that splits and produce two babies. One fertilized egg, one set of genes. Identical twins have the same DNA because they were… created when a fertilised egg split in half - so they are two identical copies of the original. Identical twins have different fingerprints because fingerprints are formed in the womb and have nothing to do with their DNA. Obviously both twins couldn't be in the same position in the womb, so their fingerprints will vary. Hope that s your question. ( Full Answer )
Identical twins are genetically the same, because they come from the same fertilized egg/sperm cell zygote, which happens to split into two viable zygotes. Fraternal twins, however, come from two different egg/sperm cell zygotes, that are concurrently fertilized and remain viable.
Identical twins can be identical, but not all the time. Sometimes one may have a pointy ear ect. But they are still identical twins. Identical twins can supposidly feel what they're twin is feeling, like, if one twin were to be in panic, the other one may feel it too. Identical twins are also known …to finish each others sentences and mirror each others movements. I'll use John and Edward Grimes for examples. (Sorry if you don't like them, but I am a big fan and know a lot about them and I can't think of any other twin examples that I can use) When they were babies, they slept in cots next to each other. One night, Edward pulled the blankets right over his head, and his twin brother, John Grimes, started screaming his head off until his mother came and seen what Edward had done. Identical twins usually chirp into their twins sentence. For an example of that go here: http://www.youtube.com/watch?v=57ek7QPx2G4 You will find they keep interupting each other, I've heard that twins usually do that to gain attention, having a twin and all. Hope that helped. ^^ ( Full Answer )
Identical twins are formed by the separation of the same embryo containing same genetic coding. thus the the twins are identical as formed from the same embryo. But this is not the case in the non-identical twins as they are formed from the individual embro each having different genetic coding.
Identical twins only have nearly identical DNA as environmentalfactors can switch genes on and off. These differences become morepronounced as the twins age. Sources: Segal, Nancy L. (1999).

They have as much chance of having twins as anyone else, regardless of who their partner is.
Whenever two babies are born at the same time, they are considered to be twins. If the two babies resulted from a single zygote that became two genetically identical fetuses, the result is identical twins (who will be very similar in appearance and who will always be of the same gender). If, however…, the two babies are the result of two separate zygotes which happened to be formed at about the same time by the fertilization of two separate ova, then the result is fraternal twins (who resemble each other only to the extent that any sibling resembles another sibling, and who are not necessarily of the same gender, which is to say, they can be brother and sister). ( Full Answer )
I dont think there is such a thing as paternal twins...perhaps you are thinking of fraternal twins. In that case, they are not identical twins, they do not look the same and they can be different sexes.
One aim is to provide more information on the "Nature/Nurture" debate: how much of a person's character is genetically pre-determined (nature) and how much is influenced by the way in which they are brought up (nurture).
No, even though twins do have identical DNA, they can have far different environments and life experiences. So, two identical twins though genetically the same could be very dissimilar in intelligence.
No. I have to really good friends that are identical twins. One is the "good, straight A student" and the other is the "bad, get into trouble" character, but they do have a lot of similarities; they are both athletic and they have the same sense of humor. So, not IDENTICAL attitudes, but similar.
Well, as an identical twin myself, I believe there is a one out of twelve chance of having identical twins, although, I'm not 100% sure....
IDENTICAL TWINS splash from 1 fertilized egg and flaternal twins splash from 2 fretilized eggs.identical twins have same DNA while flaternal twins do not have same DNA.
How do you ask a girl out who has an identical twin without the relationship being a little strange?
Walk up to her and be like 'Hey ________!' (insert name in blank) and if she's like, 'uh that's my sister' then you know you are asking the wrong girl. And to keep it from being a little strange talk to her (if you guys are friends this should be pretty easy) and ask her what little quirks her an…d her sister have that help their parents tell them apart. Pay attention to their hair that day and what they are wearing. I knew a pair of identical twins and the way I told them apart was that ones eyes were closer together. You're gonna need to pay attention to the little details on this one. It is very important that you can tell them apart. The girl that you like, if she has mutual feelings, will feel insulted if you mistaken her sister for her. ( Full Answer )
Some twins are identical twins, other are not identical twins. Identical twins develop from a single fertilized egg that subsequently splits into two zygotes. Non-identical twins, also called fraternal twins, develop from two different fertilized eggs.
Identical twins form when fertilized eggs split. non identical twins form when separate eggs are fertilized at different times. From AU Yahoo Answers.
Conjoined twins are identical but attached to each other and may share organs depending where they are attached to the others body. Conjoined twins are attached because the egg cells have not separated properly in the mothers womb.
Identical twins are two children born of one egg and one sperm, that splits early on and then separates, each half then developing into a full organism. Since they came from only one egg and one sperm, their genes will be identical. Fraternal twins are two children born of two eggs and two sperms…, each of them developing into a full organism. Since they did not come from only one egg and one sperm, their genes will be different. They could even be opposite sexes. ( Full Answer )
That would be a very unusual situation. Note that due to the normal process of genetic reshuffling that is involved in human reproduction, the children of the two couples would not be genetically identical even though their parents are.
No. Boys and girls are different, so they cannot be "identical" twins. At the cellular level, a female has two "X" chromosomes, while a male has one "X" and one "Y" chromosome.
Twins are not necessarily identical. They can be fraternal as well. Identical twins result when one fertilized egg splits in two. Fraternal twins result from two fertilized eggs.
Identical twins are created when 1 eggs splits into 2. Conjoined twins are the result of identical twins not separating all the way.
Nothing in particular. Each identical twin would be as much likeone of his brothers or sisters as one of them would be like any oftheir other brothers or sisters.
Identical twins, due to the fact that the one fertilized eggsplits, have identical DNA. Fraternal twins, since they are fromseparate eggs, have different DNA.
