Gender as Genetic
While talking with my coworker about family and genealogy, she uttered the phrase "boys run in the family" in reference to her fiance's dad and uncles having sons almost exclusively. I laughed at her at first, thinking her assertion that sex is genetic was ludicrous.
But as I thought about it more, I wondered, is one's sex genetic? I know that sex is determined from the male's sperm, without any input from the female's egg. But is the tendency to manufacture more male-producing sperm a genetic trait? Or are my coworkers soon-to-be in-laws just a statistical anomaly?

Pls research this and find out, okay? :)
ReplyDeleteMy gparents had six sons and one daughter. Of their grandkids, a vast majority are boys (I'd say about 2:1 and we're talking about 30+ cousins).
It seems that males run in our family too. I've never known if it was something in my gpa's sperm or if it was just random and then even more random that all his sons had sons too.

I'll see what I can find, hb.
