If the father has type A blood and mother type O and they have childred with type A are they Diploid haploid Heterozygous or Homozygous?

Answer 1

all type A children born in this condition are A heterozygous .

there is two possibilities with the father genes but both give us the same result, since we don't know the father blood type is hetero or homo :

if Father is Hetero :

1- Father(IAi --> A) and Mother(ii --> O), the Children are

50% of the kids will be O

50% of the kids will be A ( hetero)

if Father is Homo :

2- Father(IAIA --> A) and Mother(ii --> O), the Children are

100% of the kids will be A ( hetero)

so in both cases weither the father is homo or hetero, children will be hetero, because of the mother blood type.
