There is no such thing as "semi-identical" twins. If fraternal twins each take a paternity test, only the real father would show up as the father.
Identical twins will have the same father, so a paternity test is done just like for any kid. With fraternal twins, it is possible, but very, very rare, to have different fathers for the babies.
If they were not then they would not be called identical twins!
Identical twins would have the most genetic similarities, since they share the same original 46 chromosomes.
My guess, based on my own research into identical twins and paternity identification: sod-all. As identical twins have identical DNA, there is no way of proving who the father is. Even if the other twin says he could be the father, I think it would still wind up going through the courts - and there is still no way of proving who is the real father.
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.
Acctually, they're children would not look like twins. But all of their children would look like brothers and sisters.
Fingerprints are different in identical twins.

Yes, it is possible. It would be more common if the twins are fraternal that only one twin would be affected by the disease because it is a recessive trait, meaning both parents must be a carrier for the offspring to be affected. If the twins are identical and the tay-sachs gene is present, then boths twins will be infected because identical twins have identical DNA
Identical twins have the same DNA - meaning that without the effects of environment they would be identical in every single way.
Identical twins are born together, and look exactly alike.Nonidentical twins are born together, but do not look exactly alike.A good example of non identical would be boy and girl twins,
When a mother gives birth to identical twins, it typically results from a single fertilized egg that splits into two embryos. Therefore, only one egg is released during the ovulation process that leads to the birth of identical twins. In contrast, fraternal twins arise from two separate eggs being fertilized by two sperm cells.
