Question

For a person who is heterozygous Aa, the phenotype is:

A. The same as the phenotype of a homozygous aa person.

B. Intermediate – halfway between the phenotypes of the two homozygous individuals.

C. The same as the phenotype of a homozygous AA person.

Answer 1

Answer: c. The same as the phenotype of a homozygous AA person.

Explanation: The capital A represents the dominant property of the person’s genes. The lowercase a is recessive. This means that the dominant quality will always trump the recessive quality. That is why they are the same as the homozygous AA person.
