>>18732420I'm only interested in RH- blood types because other blood types would biologically reject a child made with my magical semen. You also want to make sure that you can be a blood donor to your kid, or vise versa.
Two O types will make an O child
Two A types will make an A or O child
Two B types will make a B or O child
If any of these have a negative RH factor, both parents must have it or the mother will reject the offspring in her womb.
If you are Type O with RH+, and your wife is O RH-, her body will reject the child as if it were alien.
For me, the only suitable partners would be
>blond or red hair>blue or green eyes>pure west European lineage>RH- blood
