Question

A diploid organism is heterozygous for 5 gene loci and homozygous for 2 loci, how many types of gametes can be produced?

• A. 128
• B. 32
• C. 4
• D. 14

Answer 1

The correct option is B 32

Organism heterozygous for 5 loci represents pentahybrid condition.
The types of gametes are calculated using the formula, 2${}^n$ , where n is number of heterozygous gene loci, hence $(2{)}^5=32$.
The types of gametes produced will be 32.
