"Those identical cells grow into identical twins," says Scott.What would happen if identical twins had a kid together?
"In theory, we would expect their children to be genetically as similar as full siblings are to each other," said Laura Almasy, a professor of genetics at the University of Pennsylvania. Siblings born to the same set of parents share about half their genes with one another.Can identical twins give birth to twins?
A pair of sisters from Utah have taken the notion that twins do everything together to a new level. Identical twins Kelli Wall and Kerri Bunker, 36, each gave birth to twins of their own within the last six weeks.

Why do twins skip a generation?
This belief is based on the assumption that twinning is genetic and runs in families.

There is no concrete scientific evidence that suggests twins skip a generation.What happens if identical twins have a baby with identical twins?
"Twins married to twins who both have babies at the same time." Since identical twins share the same DNA, the children of two pairs of identical twins are legally cousins, but genetically more similar to siblings.What are Irish twins?

Everyone has the same chance of having identical twins: about 1 in 250. Identical twins do not run in families.Do identical twins have 100% the same DNA?
Identical twins form from the same egg and get the same genetic material from their parents — but that doesn't mean they're genetically identical by the time they're born.What is special about identical twins?
Identical twins have DNA that is 99.9% the same. They also have almost nearly identical brain wave patterns. But they do have different fingerprints and teeth marks! 22% of twins are left-handed as opposed to the 10% of singletons who turn out to be left-handed.Do identical twins have the same personality?
Thus identical twins, though they start with the same genes, likely develop different personalities in the same environment partially based on how they interact with their environment.Can I have twins if there is no family history?
