Question

Mom is heterozygous A and dad is type AB blood type. Do the Punnett square. What are the chances the offspring will be type B

Answer 1

Dad is type AB

Mom is heterozygous type A which is Ao

after drawing the punnet square (the image attached) you will find that mom and dad produced offsprings with the genotypes: AA, AB, Ao, and Bo

Parent AB X Ao offspring probabilities

1/4 type AB (25%)

1/4 type B (25%)

1/2 type A (50%)
