My father is B
My mother is A
My eldest brother was A
My older brother is B
I'm O

Does that make my father Bo, and my mother Ao, meaning both MUST be O recessive?

Also, my wife is A.
So does that make my daughter A? Unless my wife is O recessive, in which case my daughter may be O?

absolutely meaning my folks must be O recessive?

but how did my brothers become A and B respectively?

i thought A was dominant. how did my middle brother become B?

still confused...should have paid better attention in HS biology  :)

A plus o recessive makes an A
B plus o recessive makes a B

both your parents have o recessive genes...voila!

A and B are dominant, not just A

Your daughter can either be an A or an O, since you're an O (each sperm cell having an allele for O) and your wife is an A (each egg having either an A or an O if she's AO, or each egg having an A if she's AA, in which case all your kids will be As.)

With one parent being an A and  the other parent being a B, you could have had a sibling with type AB blood as well.

I wouldn't put too much stock in the "blood type personality" thing. My two O daughters are VERY different from one another, and my B son is very much like my younger daughter. Just from guessing, I would have thought that DD2 and DS were one type and DD1 was another. But blood typing showed otherwise. All are much more evenly tempered when they're eating right for their types.
