Question

Please please help !
If a husband has an (AB) blood type, and his wife has a dormant (A) blood type, what will the possibility of their children’s blood types be?

Answer 1

Blood type A can be due to I(A) I(A) or I(A) I(O). A is for A allele, O is for O allele.
next, draw genetic pedigree diagram or punnett square.

I always use punnett square because is simple.
If is I(A) I(A),
if is I(A) I(O),
