In humans, large eyes A dominate small a, long eyelashes B dominate short b. what is the genotype of a father who has big eyes with short eyelashes, if in a marriage with a woman with small eyes and long eyelashes, he only had big-eyed children with long eyelashes? what is the genotype of the parents?

A woman with small eyes will have, according to the conventional designation, the homozygous genotype aa, because the trait she demonstrates belongs to the category of recessive.

Such a woman will pass on to the descendants only the gene for small eyes a.

Father’s short eyelashes are due to homozygosity for the b gene. He can only transfer such a gene to offspring.

Thus, all large-eyed children with long eyelashes have a heterozygous genotype – AaBb.

Since all the offspring of a given married couple is uniform, it should be concluded that the parents are homozygous for the genes that determine the development of their dominant traits.

Mother will be aaBB, father – Aabb.
