Question

Match List-I with List-II

List-I (Particulars) & List-II (Formula used)
(A) Number of individuals in a perfect $F_2$ population & (III) $4^n$
(B) Number of perfect homozygous individuals in an $F_2$ population & (I) $2^n$
(C) Number of different heterozygous genotypes in an $F_2$ population & (IV) $3^n - 2^n$
(D) Number of different kinds of genotypes in an $F_2$ population & (II) $3^n$

• (A) - (I), (B) - (III), (C) - (II), (D) - (IV)
• (A) - (IV), (B) - (I), (C) - (III), (D) - (II)
• (A) - (III), (B) - (I), (C) - (IV), (D) - (II)
• (A) - (III), (B) - (IV), (C) - (I), (D) - (II)

Hint:

For $n$ segregating genes:
- Number of $F_2$ genotypes = $3^n$
- Number of homozygous genotypes = $2^n$
- Number of heterozygous genotypes = Total $-$ Homozygous = $3^n - 2^n$
- Minimum $F_2$ population size = $4^n$
