Answer 1

I love posts like this. Both mom and dad are O+, I’m AB-, I went so far as to have genetic testing done a couple of times just to verify that I was actually my parents kid when I found out what my blood type is because of the difference, so somewhere in my genetic line an A, B, and a -rh were present and I got them all lol. All my other siblings are O+, so I’m the oddball of the family (in more than 1 way lol).
