Question

What will be the number of genotype in $F_2$ generation if a character is controlled by 4 pairs of polygenes?

• A. 16
• B. 9
• C. 25
• D. 61

Answer 1

Answer: (A)

16

• The number of genotypes in F${}_2$ generation is given by the formula N$2$ where 'N' represents the number of genes.
• Here, N=4 hence going by the formula we get the number of genotypes as 16.
• So, the correct option is '16'.
