In humans, dark hair color (A) dominates over light color (a), brown eye color (B) dominates over blue (b). Write down the parental genotypes, possible phenotypes and genotypes of children born from the marriage of a fair-haired blue-eyed man and a heterozygous brown-eyed fair-haired woman.
1) Parent genotypes: 1) Female: aaBb (gives two types of gametes aB; ab. Male: aabb (one type of gametes ab).
2) Offspring genotypes: aabb, aaBb.
3) Phenotypes of offspring: aabb – fair-haired, blue-eyed;
aaBb – fair-haired, brown-eyed.
