Answer: The possible genotypes for brown-eyed babies are BB and Bb while the possible genotype for blue-eyed babies is bb.
Explanation: From the information given above, B = allele for brown-eyes, B is dominant while b = allele for blue-eyes, b is recessive. A dominant allele is one that expresses itself in the presence of a recessive allele, it masks the effect of a recessive allele while a recessive allele is one that cannot express itself in the presence of a dominant allele, its effect is masked by a dominant allele. A recessive allele can only express itself in a homozygous state while a dominant allele expresses itself both in a homozygous and heterozygous state.
Brown-eyed babies will therefore have two possible genotypes: BB and Bb while blue-eyed babies will have one possible genotype: bb.
