Dear Matt:

I was wondering. If a set of identical twins married another set of identical twins, and each couple had a child, would the two children be identical?

UCSD's medical genetics department I'm sure has bigger fish to fry, but they took time out from the important stuff to say that the children of your hypothetical lovebirds would look bout as much alike as any other siblings. As the great genetic wheel of fortune spins, each pair having one child would be roughly the same as two single births from one couple Over some infinite number of pregnancies, the couples would produce kids who were genetically identical, but that scenario has more to do with statistics than reality. And it would just confuse the heck out of the relatives anyway.
