Answer to Question #166353 in Genetics for Vishnu Ganta

Question

 Predict the blood group of the offsprings when father is heterozygous A and mother is heterozygous B.

Answer 1

Heterozygous A is AO

Heterozygous B is BO

Possibilities for offspring are:

AO 25%

BO 25%

AB 25%

OO 25%

So there is a 25% chance the offspring will be AB and a 25% chance the offspring will be OO. That adds up to a 50% chance that the baby will end up with a different ABO blood type as either parent.
