Question

The number of different types of gametes that can be produced by an organism with genotype $AaBbCcDd$ is

• A. $4$
• B. $8$
• C. $12$
• D. $16$
• E. $20$

Answer 1

The correct option is D $16$

Total types of gametes that an organism can produce is represented by $2^n$. Here, n= number of genes for which the organism is heterozygous. The given genotype AaBbCcDd is heterozygous for 4 genes and can make $2^4$= 16 types of gametes. Thus, the correct answer is option D.
