cristie is right....if they are both AA, then they will produce AA kids. if both are AO then even though the blood has the A protein the kids could inherit AA, AO, or OO....if OO is inherited than you can have an O child. +/- works the same....if you are both ++ than you will only have ++ kids. if you are +- then you could have either + or - kids. i study genetics, so i am really familiar with this stuff.
