Question

If individuals of genotype Aa Bb Cc are intercrossed, how many different phenotypes can appear in their offspring?

Options

• 3

• 6

• 8

• 16

Answer 1

8

Explanation:

For individuals with genotype Aa Bb Cc, each gene pair shows two phenotypes (dominant or recessive). Since the genes assort independently, the total number of different phenotypes is 2 × 2 × 2 = 8. Thus, 8 distinct phenotypes can appear in the offspring due to all possible combinations of dominant and recessive alleles for the three genes.
