If identical twins married identical twins what would their childrens dna show as? cousins or siblings?
we have this in our family. The children who are first cousins all look very alike. If one was looking at their DNA, wouldnt it show as siblings since their mothers and fathers both had identical dna?
how would one know they were cousins just by the dna alone?

Their DNA would look as though they were siblings even though they are actually cousins.
Wouldn't be possible to tell they were cousins instead of siblings from DNA testing alone.
There is a website called twinstuff that was founded by ID twin brothers who married ID twin sisters. One of the brothers and his wife have ID twins.
They have a forum called twin wiki that has alot of other FAQ on this subject.

I don't know if you would be able to tell they are cousins and not siblings by their DNA alone. I would say it would look like they are siblings. Wow that is pretty cool...
