Question

A diploid organism is heterozygous for 4 loci; how many types of gametes can be produced?

Answer 1

For a diploid organism, which is heterozygous for 4 loci, then 2⁴, i.e., 2 × 2 × 2 × 2 = 16 types of gametes, can be produced if the genes are not linked, because for each heterozygous pair of genes, there are two possibilities.

Thus for 4 pairs, the number of possible gamete combinations is 16.
