Can Ami have the B blood type?

To determine whether Ami can have the B blood type, it's essential to understand how blood types are inherited. Blood type is determined by the presence of specific antigens on the surface of red blood cells, which are genetically inherited from an individual's parents.

A person's blood type is classified as A, B, AB, or O, depending on the alleles they receive. The B blood type can be expressed if an individual inherits a B allele from one or both parents. Individuals with blood type B can have genotypes of either homozygous (BB) or heterozygous (BO), where O is a recessive allele.

If Ami is to have the B blood type, she must inherit at least one B allele from her parents. If both parents do not carry the B allele (for instance, if they are both type A or O), then Ami cannot have the B blood type. This takes us to the conclusion that the answer is that Ami cannot have the B blood type if neither of her parents can contribute that B allele.

Thus, without at least one parent having the B factor in their genetic makeup, Ami's blood type cannot be B, making the assertion that she cannot have the B blood type accurate.
