Question

a male fruit fly has the genotype ppyyrrtt. 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 allele pairs

Genotype: Pp (heterozygous), Yy (heterozygous), Rr (heterozygous), TT (homozygous). Heterozygous pairs: 3.

Step2: Calculate gamete types

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

Answer:

8
