Question

a male fruit fly has the genotype ppnnvvtt. in terms of these 4 allele pairs, how many different types of gametes can he form?
multiple choice
2
16
8
4

Explanation:

Step1: Identify heterozygous pairs

Genotype: PpTtVvFF. Heterozygous pairs: Pp, Tt, Vv (3 pairs). FF is homozygous.

Step2: Calculate gamete types

Number of gametes = $2^n$ (n=heterozygous pairs). $2^3 = 8$.

Answer:

8 (assuming the third option is "8")
