The answer is <span>C.Three genotypes, two phenotypes.

Imagine gene for flower colors. Let A allele be dominant and a allele be recessive allele for the trait. A allele is responsible for red color and a allele for white color

The genotypes are:
1. AA
2. Aa
3. aa

However, there will be only two phenotypes:
1. red flowers
2. white flowers

This is because of the dominance of A allele over a allele. So, red flowers will have plants with genotypes AA and Aa while white flowers will have plants with genotype aa.</span>
