Question

I have a question about blood types

Answer 1

Mary has type A blood and her husband has type B blood. Her husband's parents both had type AB. They have 3 children - one type A, one type AB and one type B. Relatives suspect one of the children is adopted. What are the parent's blood genotypes?

Answer 2

Which child was adopted? Explain.

Answer 3

husbands parents have AB blood group...so gentoype of husband is BB. and mary's blood group can be AA/AO. now if u cross both of them u cannot get blood group A because the genotype of A is AA/AO. since each offspring is going to get 1 letter from father which is B.
so the one with blood group A is adopted...
