Explanation:

Step1: Recall Hardy - Weinberg equation

The Hardy - Weinberg equation is \(p + q=1\) (for allele frequencies) and \(p^{2}+2pq + q^{2}=1\) (for genotype frequencies), where \(p\) represents the frequency of the dominant allele and \(q\) represents the frequency of the recessive allele. \(p^{2}\) is the frequency of the homozygous dominant genotype, \(2pq\) is the frequency of the heterozygous genotype, and \(q^{2}\) is the frequency of the homozygous recessive genotype.

Step2: Match the terms

• Frequency of the homozygous dominant genotype: \(p^{2}\)
• Frequency of the dominant allele: \(p\)
• Frequency of the recessive allele: \(q\)
• Frequency of the heterozygous genotype: \(2pq\)
• Frequency of the homozygous recessive genotype: \(q^{2}\)

Answer:

frequency of the homozygous dominant genotype: \(p^{2}\), frequency of the dominant allele: \(p\), frequency of the recessive allele: \(q\), frequency of the heterozygous genotype: \(2pq\), frequency of the homozygous recessive genotype: \(q^{2}\)
