Which blood type is not possible for a child with a mother of type AB and a father of type B?

A child inherits alleles from both parents, which determine their blood type. The mother has type AB blood, which means she has one A allele and one B allele. The father has type B blood, which could mean he has either two B alleles (genotype BB) or one B allele and one O allele (genotype BO).

In terms of possible allele combinations for the child:

1. If the father is BB, the possible combinations the child could inherit are:

• From mother (A) and father (B): Type AB

• From mother (B) and father (B): Type BB (Type B)

2. If the father is BO, the possible combinations are:

• From mother (A) and father (B): Type AB

• From mother (A) and father (O): Type A

• From mother (B) and father (B): Type BB (Type B)

• From mother (B) and father (O): Type B

In both scenarios, the child could end up with blood types A, B, or AB. However, blood type O is determined by inheriting two O alleles (genotype OO). Since there are no O alleles
