I'm kinda wondering if odds of XX vs XY baby is a trait on that chromosome pair. Because Dad's brother's kids are all girls, and Dad's kids are mostly girls whether one counts me as a girl or not, where Dad's sister's kids and all but one of Mom's assorted siblings' kids are boys. (As far as I know, everyone else I'm related to is cis.) So it makes intuitive sense that there's a patrilineal tendency toward XX kids on Dad's side, which is irrelevant re his sister's kids, and a patrilineal tendency toward XY kids on Mom's side, which is irrelevant re her kids and her sister's.

But also my sample size is shit.
