Question

Can a baby that has a blood type of ab have one parent that is tyoe o

Answer 1

Hello,

It is not possible .. If you need the explanation. Here it is.
Simple genetics. The parent that is Type O can only produce children with Type O blood.
The parent that is Type B can be either BB or BO and thus produce children with either Type O or Type B.
Type B is dominant to Type O, the outcome is either OO or BO.

Pls mark it if helped.
