Question

A diploid organism is heterozygous for three loci, how many types of gametes can be produced by that organism?

Options

• 4

• 8

• 16

• 32

Answer 1

8

Explanation:

An organism that is heterozygous for three loci has two alleles for each locus. The following formula is used to determine the number of distinct gametes:

2ⁿ,

Where,

n = Number of heterozygous loci

Since n = 3, the number of gametes is:

2³ = 8
