Question

If a mother is blood type O and a father is heterozygous for a blood type B, their children's blood types can be

A- B or O only
B- A, B, or O only
C-A or B only
D- A,B,O, or AB only

Answer 1

A- B or O only, because there's no type A in the parents so the kid couldn't possibly have a blood type A.

hope this helps!!!
