Question:

Would their children be genetic SIBLINGS???...?

If male identical twins were to marry female identical twins, would their children be genetic SIBLINGS?

Best Answer - Chosen by Asker: No. They would be share a lot of the same genes, but there is a lot of variation in the DNA of the human body. They might not even look like they are related!

If the egg and sperm both happened to be carrying non-dominant genes, there could be a lot of differences. They would remain first cousins. Actually, I guess they would be 'double' first cousins!
