Another puzzling question I have is this.. I have “googled” this and because I dont trust “science” … My parents and my sister are all brown hair, brown eyed and right handed and all have A+ blood. Im blonde, blue eyed, left handed and supposedly O+.. how is this possible? Googling says any blood type can produce any blood type.. something just doesn’t set well with me and that answer.

I'm brown-eyed/brown-headed, right-handed...and O-.

Stick with me. This is actually much more complex, but I think I can break it down into simpler terms that anybody can understand.

Our blood types aren't just A or B or O. We get one part from each parent. so if your parents were both A (forget the + or - for now), and you are their child and have O, then they actually are type AO and you got the O from both, so you're actually OO. Your sibs that are type A could be either AA (got an A from each parent) or they could be AO (got an A from one parent and an O from the other) - either way they would still just have "type A blood". See how that works? 👍😉

The + or - is the Rh factor. If EITHER parent is positive, their children will be, too. 👨‍👩‍👧‍👦

Your hair color/eye color/dominant hand have nothing to do with blood type. You just got lucky with a different gene expression (dominant vs recessive and all of that).
