Any set of twins that are not identical (whether it's boys or girls or a combination of the two) are fraternal twins.
Fraternal twins are created when 2 separate eggs are fertilized. Identical twins are created when 1 fertilized egg splits into 2. It is impossible for one identical twin to be male and the other female. Identical twins are usually the ones that look exactly alike.
there is no such thing as paternal or maternal twins. the only type of twins there are is fraternal, and Identical. Identical twins are the result of one sperm fertilizing one egg and that fertilized embryo splitting apart and forming two fetuses, therefore the children are born identical, and thus must be of the same sex. Fraternal twins are the result of two eggs being fertilized at the same time by two different sperm, and the children will be born different from the other. As a result, they can be male/male, female/female, or female/male. also there is a very slim chance that fraternal twins can have two different fathers, as it can take up to two weeks after having sex for a sperm to fertilize an egg. so if a female has sex with multiple partners, there is a very small chance that the two twins could be from two fathers. just to clarify... there is no such thing as paternal or maternal twins

If You Are A Twin (Or Have Twins In Your Family): If you are a fraternal twin, you have a 1 in 17 Chance of having twins. If you are identical, it doesn't affect your chances, and they remain from 1 in anywhere from 38 - 90, depending on if fertility drugs are used or not. If your mother is a fraternal twin, you may have a higher than average chance of twins. If you father is a twin, it doesn't affect your chances, as fraternal twinning is apparently carried down the maternal line. If your husband is a twin or has twins in his family, it doesn't affect your chances of having twins. If you have a parent that is an identical twin, your chances of having twins yourself are the same as anyone else.
It is called the ovum. Occasionally, two are released, which may yield fraternal twins if both are fertilized.
I have a female Yorkie (maternal) and pekineses (fraternal) and the only time she looses hair is when I brush her... I don't have a problem with her shedding... So I think its hard to say yes or no it depends on the genetics I think...
Luck. There is no way of having identical twins, let alone choosing the sex. 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. Fertility drugs also make this more likely to happen.
No. Conjoined twins are always identical twins, and never just fraternal twins. Identical twins come from a single embryo that splits. In the case of conjoined twins, a complete split never occurs. So when they come from the same embryo, they are always the same gender.
First part of my answer is that wattles are a genetic characteristic. They are not normal. Cute, painless, etc., but most goats don't have them. Second part is the easy one. They aren't identical twins. They're fraternal.
There are at least three ways to produce twins. One is when the female produces two eggs, both of which are fertilized by the male. This is how fraternal twins are produced. Fraternal twins can be both the same sex or different sexes. Fraternal twins may only bear a slight resemblance to one another, no more than any two siblings might. (Fraternal twins can actually have different biological fathers, because the eggs may be produced a day or two apart.) Another is for the woman to produce one egg which is fertilized by the male, and then the egg divides into two. This is the traditional way that so-called identical twins are produced. Identical twins are always the same sex. (I use the term 'so-called,' because they are actually 'mirror image' twins.) A third way is for the woman to produce one egg, which then divides into two, which are both subsequently fertilized. There is a greater chance that such twins will resemble one another than fraternal twins, and they may be the same or opposite sexes.
The male side is the paternal side and the female side is the maternal side.
Sexual prorogation of plants (reproduction) is when a seed is produced inside the flower by using pollen (from the stamen) and a pistil (female part). Asexual prorogation is when a plant uses vegetative parts to produce more plants. There are many different way this happens.
Your father's mother is your paternal grandmother. Your mother's mother is your maternal grandmother.Paternal on the male side. Maternal on the female side.
Fraternal twins are produced when the female double ovulates and a different sperm fertilizes each egg. They can be the same sex or each a different sex. They are, of course nonidentical. There is a 1 in about 80 chance of a twin pregnancy although the tendency runs in families. Identical twins are produced from a single fertilized egg that divides into two separate conceptus during early development.
They don't. There are two types of twins, fraternal and identical. Current research shows no genetic connection to having Identical twins, anyone can have them. Fraternal twins are caused by a female trait, dropping more than one egg at a time. There appears to be evidence that the trait can be inherited. While it appears to be on the mother's side of the family, it is certainly possible that this could be transmitted on the male side as well. This double dropping also occurs with older women as well.
Your mother's uncle, whether maternal or paternal, is your great uncle. You are his great nephew if you are male, and his great niece if you are female.
Just about anyone can have twins. However, when twins "run in the family", it only runs in the FEMALE half of the family. If your mother is a twin who has a mother who is a twin, and you're female, you have a higher chance of having twins yourself. If you're male, it doesn't matter. Only the female can "decide" to have twins or not -- the male is not included in the decision. (By "decision" I mean how the female's body releases her eggs or how the eggs divide.) There are two types of twins. Identical and fraternal. Identical occurs when a single fertilized egg develops into two embryos. Fraternal occurs when two eggs are fertilized. If fraternal twins run in a woman's family there may be a familial tendency to release more than one egg at a time and she may have a greater chance of having twins. Identical twins 'running' in a family is far less common. Many things can influence the likelihood of twins. The most typical being fertility drugs. A woman's age and parity (how many children she has already had) can also affect the likelihood of twins.
MZ twins are identical twins that share 100% of the same DNA. DZ twins share only 50% of their DNA (fraternal twins). MZ twins are always the same gender, whereas DZ twins can be the same gender or one male and one female. DZM would be the male pairing of DZ twins, DZF is the female pairing, and DZO is when there is a male and a female.

No. Conjoined twins are always identical twins. Identical twins are always the same sex.
Neither the husband, nor his family history of twins, will have any effect on his sons fathering twins. Whether or not a pregnancy is twins, triplets, etc., depends entirely on the woman. What determines twins (or triplets) is if one egg is fertilized, then splits in two, then this is identical twins; if the egg splits in three, then it's identical triplets. If two eggs are fertilized, then they will be fraternal twins, and not identical, and may not even resemble each other at all; they can even be a different sex from each other. If three eggs are fertilized, then they will be fraternal triplets, and not identical, and can be all female, all male or two of one sex and one of another. The bottom line is, the father neverhas anything to do with whether or not it's a single birth, twins, triplets, etc. It is the mother, and the mother only. Now if multiple birth pregnancies run in her family, then the chances of twins will be higher than families with no history of multiple births.
Although there can be the usual resemblance of a family, they cannot be both "identical" twins and different genders.
a female shark is called a female.
they are identical in appearance,but females grow larger.
It's two identical female angels.
