The percentage of the population that is homozygous dominant

Detailed explanation-1: -The frequency of the recessive allele. Answer: Since we believe that the homozygous recessive for this gene (q2) represents 4% (i.e. = 0.04), the square root (q) is 0.2 (20%). The frequency of the dominant allele.
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: -This is q2. Answer: Four of the sixteen individuals show the recessive phenotype, so the correct answer is 25% or 0.25.
Detailed explanation-4: -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.
