Gene B (III) of blood group IB dominates over gene Io. A man homozygous for B (III)

Gene B (III) of blood group IB dominates over gene Io. A man homozygous for B (III) blood group, married a woman with first blood group. What could be the genotypes of their children?

Homozygous, according to the condition of the problem, for blood group III, a man has the genotype I B I B and produces spermatozoa of the same type – I B.

A woman with blood group I has a genotype I o I o and produces eggs of only one type – I o.

All offspring of this married couple will be geno- and phenotypically uniform and represented by children with blood group III and genotype I BI o.
