I am one of these folks that claims natural math/development skills which were inherited from my natural parents. Here is my empirical evidence:
I was neither raised by or knew my biological family growing up (though I know them now). My mother is a developer, my supposed bio-dad is a developer, my late grandmother on my mother's side was a mathematician & psychologist, my grandfather on my mother's side was on the early teams at IBM, and my uncle whom is close to a doppelganger of me is a developer/linux admin. I knew none of these people growing up. My father and mother who raised me are respectively a restaurant manager and a hair stylist. Neither have any significant interest in the sciences or mathematics realms. Somehow I ended up in the family business without a shred of influence from them.
Take my story for what you want, but in this case the women were very much involved with the biological version.
