Question

Consider a gene with two alleles, one is dominant (A) and one is recessive (a). The offspring of a homozygous dominant (AA) individual can have how many phenotypes?

Answer 1

The offspring of a homozygous dominant (AA) individual can have one phenotype.

Step-by-step explanation:

The offspring of a homozygous dominant (AA) individual can have one phenotype.

When an individual is homozygous dominant for a gene, it means that both alleles for that gene are dominant. In this case, because the dominant allele is always expressed in the phenotype, there is only one possible phenotype.

For example, if the gene in question determines eye color and the dominant allele represents brown eyes, then all offspring of a homozygous dominant individual would have brown eyes.
