What is the possibility of two heterozygous parents having identical twins?
Heterozygous parents have the same odds of identical twins as the general population. Identical twins do not run in families and, therefore, twinning is not related to genetics. Comparisons among different ethnic groups rule out an ethnic cause-no difference. Only mother's age correlates with twinning: the older the mother, the greater the likelihood.
Why identical twins are similar?
If they were not then they would not be called identical twins!
Why are identical twins and fraternal twins not the exact same?
Identical twins are formed from a single egg that splits into two. Fraternal twins are formed from two separate eggs that are both separately fertilized. So identical twins have identical DNA, and fraternal twins do not.
What is the odds of twins children having twins?
The fact that twins run in families is actually a myth. The odds of twins having twins is the same as a non-twin having twins. That is about 1 in 33.
Why are the twins identical?
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.
Are twins more likely to have twins for their own child?
I have an identical twin. For me it is no more likely that I will have twins than anyone else because identical twins are just flukes. If you are a non- identical twin and that is because your mother had two eggs, then you may have this too, and it is more likely you will have twins.
What is the percentage of identical twins?
Identical twins make up about 0.2% of the world's population. This means that approximately 1 in every 250 births results in identical twins.
What are the odds of twins haven twins?
The odds are 75 percent.
What are the odds of having twins twice?
From what i know, if your twins are identical then you have no increased chance of having twins a second time. If your twins are fraternal, you are twice as likely to have twins again because fraternal twins are the result of more than egg being released and that is a genetic trate.
What are two horses with identical genes called?
Identical twins. Although horses sometimes have twins I'm not sure if they have identical twins.

How are twins identical?
Twins are identical because they come from the same egg.

How do you get identical and non identical twins?
Identical twins are formed when one fertilized eggs splits. Non-identical twins are formed when two separate eggs are fertilized.
What is the chance of you having twins if your boyfriend is a twin?
it has nothing to do with the father of the baby AT ALL! it depends on the Mommy's body. you have to either produce 2 eggs (which means fraternal twins) or have 1 egg that splits into 2 (which is identical)... all that depends on the father is whether or not he fertilizes both... though those genes can pass onto your children.
If I had identical twins 3 years ago what are my changes of having another set of identical twins?
The same as when you had the first set of identical twins.
