Question

If an organism has the genotype RrSsTtUu, how many different types of gametes will be produced, assuming independent assortment of chromosomes?

• A. 4
• B. 8
• C. 9
• D. 12
• E. 16

Answer 1

Answer: (E)

16

For a given genotype, number of different type of gametes formed can be calculated as 2${}^n$ (where n is the number of heterozygous genes).

For the genotype RrSsTtUu, n is 4. Therefore, different types of gametes produced will be = 2${}^4$ = 16

So, the correct answer is '16'.
