If my identical twin brother married my wife's identical twin sister, both couples would have an above-average chance of having twins among their children. Beyond that, our collective set of children would have as much genetic variation as the same total number of children born to any unrelated couple. Siblings don't all look alike.

They would also have identical twin children... because they both have the twin jean.

I dont think it would be incest or anything, but as for the chance they have twins etc. is probably good, i know 2 sisters that had children with 2 brothers, theyre children are cute as hell and dont look like eachother.............if that helps

The children would look entirely different, for them to look similar the same egg would have to split 4 times, therefore impossible because both women have seperate eggs. There's an article about it on popsci.com, try looking there.

the babies could certainly no longer be comparable, any further than the babies of non-twins could be comparable. each sperm cellular and each egg cellular contains diverse genetic opportunities. it extremely isn't any diverse with twins. there is not any such factor as "comparable cousins." That improve into purely a television prepare.

The kids would genetically all be siblings. I think I saw this on a talk show once.

Their offspring would be mutants, each with multiple heads, 14 toes, 11.5 fingers, and a third arm growing out of their foreheads.
