In humans, the brown-eyed gene is dominant. Determine the genotypes and phenotypes of children in the following

In humans, the brown-eyed gene is dominant. Determine the genotypes and phenotypes of children in the following cases: a) both brown-eyed homozygotes b) both parents are heterozygotes c) one is heterozygous. and the other blue-eyed

In the first case, all children: Phenotype-brown-eyed, genotype AA- brown-eyed Brown-eyed – 100%
In the second case, children: The phenotype is either blue-eyed or brown-eyed, genotype AA- brown-eyed, A- brown-eyed, a- blue-eyed
Brown-eyed – 75%, blue-eyed – 25%
In the third case, children: Phenotype – brown-eyed or blue-eyed, genotype – A- brown-eyed, a- blue-eyed
Brown-eyed – 50%, blue-eyed – 25%
