Question

In a group of cows, some individuals have horns and others do not. In this group, the gene for the horns trait has two alleles. The allele for not having horns (H) is dominant over the allele for having horns (h).

Aphrodite is a cow from this group. Aphrodite has the homozygous genotype HH for the horns gene.
Based on this information, what is Aphrodite's phenotype for the horns trait?

Answer 1

Aphrodite, having a homozygous dominant genotype (HH) for the horns trait in cows, will express the dominant phenotype of not having horns.

Step-by-step explanation:

Aphrodite is a cow that has the homozygous genotype HH for the horns gene. In Mendelian genetics, when an individual is homozygous dominant (HH), they express the dominant phenotype. Since the allele for not having horns (H) is dominant over the allele for having horns (h), Aphrodite's phenotype will be not having horns. Even though the gene for the horns trait has two alleles, only the dominant one is expressed in the phenotype when an individual is homozygous dominant or heterozygous.
