Here's a random question out of curiousity haha
If a woman had sex with identical twin males, say with each one within a day apart and she became pregnant, would it be possible to tell who the father is? I know twins have the same DNA but other things about them are different, like their finger prints. (link)

Twins are not identical DNAs they do share genes
"there in fact are tiny differences and that they are relatively common," said researcher Jan Dumanski, a molecular geneticist at the University of Alabama at Birmingham.
In the new study, researchers analyzed 19 pairs of identical twins. Although they did possess nearly identical genomes, closer study revealed they often differed in the number of copies of individual gene segments. For instance, one twin might be missing a segment, or possess more copies of that segment than the other twin.
Such variations could explain why one identical twin can suffer from a disorder while the other remains healthy. Researcher Carl Bruder expected that even identical twins that appear completely alike harbor "copy number variations" when it comes to at least one site in their genomes.

twins DO have identical DNA but have different genotypes, meaning a DNA test cannot tell them apart but looking at their finger prints could.
