Same logic goes as far as baby mommas grandparents, only one needs to carry the blue eyed gene.
So if only one of her grandparents carried the recessive Gg gene, and the other three were GG; that one g gene must have been passed to one of her parents. Then when her parents met, the one that carried Gg, must have give the "g" gene to her. Then when she met you, your "g" combines with her "g."
If baby mommas mother is GG and father is Gg or gG, then baby momma will have a 50% of carrying recessive Gg eye color gene, 50% chance of carrying GG gene. Since we know baby has blue eyes, then we can conclusively infer baby momma is not GG.
Only one parent must have "g" if the child carries it. Both must have it if the child displays blue eyes. Does that make sense?
That science stuff reminded me of HS. I understand what you're staying fully. I just thought it was funny because no one of her greats or mine has it. You good people, Hous. You remember that other site? Good God!!!!
