In the Hardy-Weinberg equation, which of the following represents homozygous recessive traits?
A
B
C
D
1
Explanation: 

Detailed explanation-1: -Hardy Weinberg equation says, p2+2pq+q2=1, where q2 is the frequency of homozygous recessive gene.

Detailed explanation-2: -In the equation, p2 represents the frequency of the homozygous genotype AA, q2 represents the frequency of the homozygous genotype aa, and 2pq represents the frequency of the heterozygous genotype Aa.

Detailed explanation-3: -Answer and Explanation: In the Hardy-Weinberg Theorem it states p2 +2pq + q2 = 1. p2 represents the frequency of the homozygous dominant genotype, q2 represents the frequency of the homozygous recessive genotype, and 2pq represents the frequency of the heterozygous genotype.

Detailed explanation-4: -Hardy-Weinberg Equations The variable ‘p2’ denotes the homozygous dominant genotype (AA), ‘2pq’ denotes the heterozygous genotype (Aa), and ‘q2’ denotes the homozygous recessive genotype (aa). The following conclusions can be inferred through this law: Only sexual reproduction is possible. Mating is a random process.

Detailed explanation-5: -We know that the frequency of the recessive homozygote genotype is q2 and equal to 0.09.
