Question

How many different types of gametes are produced by the genotype $AaVv$?

• A. 1
• B. 2
• C. 4
• D. 6
• E. 8

Answer 1

Answer: (C)

4

Types of gametes produced by an organism= $2^n$ where n= number of genes for which the organism is heterozygous. The given genotype "AaVv" is heterozygous for 2 genes; total types of gamete produced by it= $2^2$= 4 (AV, Av, aV and av). Thus, the correct answer is option C.
