I just read a really interesting factoid:
Identical twins' children are genetically SIBLINGS*, not cousins.
Well if you think about it, Asher and Nolan are genetically the same person. What started out as one baby became two. Therefore, when those "same persons" procreate, the children they produce are siblings*, not cousins, from a genetic standpoint at least.
*Let me clarify here - by siblings I mean HALF-siblings (I just prefer the shock value). The only way they would be full genetic siblings is if the boys had babies with the same mother or if they had babies with another set of identical twins. Possible? Sure. Probable? God help me, I hope not! This is weird enough as it is.
I love me some identical twins. The freakiness is never ending!
