Question

A man with Type B blood has children with a woman with type A blood. Their children have the following blood types, A, AB, B, and O. What are the genotypes of the parents? What would be the genotypes of the parents if the offspring could only have type AB or A blood

Answer 1

Explanation:

only when both alleles is O, the blood group can be O. Thus both parents must have O as one allele

Thus man's genotype: BO or

${ | }^{b} i$

Woman's genotype : AO or

${ | }^{a} i$

When

the children can not have O blood

The children cannot have B blood

means the man have BO

${ | }^{b} i$

and woman have AA

${ | }^{a} { | }^{a}$

Because

if man have BB, and woman have AA

children can only have AB

if man have BB, and woman have AO

children can only have AB and B
