No, it doesn't apply to humans. Either the female twins you know didn't want kids, or something else was going on.uncle Will in In. said:Do any of you know if this applies to humans. I know of quite a few boy girl twins where the girl never had any children. I also know a lady who had a twin brother, and she had 4 sets of twins and 3 singles.. However one set of her twin offspring was a boy-girl combination, and the girl never had children.
What can anyone tell me about this?
