Explain what terms in the Hardy-Weinberg equation give: allele frequencies (dominant allele, recessive allele, etc.) each genotype frequency (homozygous dominant, heterozygous, etc.) each phenotype frequency

Hardy Weinberg equilibrium states that in a population the amount of genetic variation remains constant from one generation to another generation in the absence of evolutionary disturbances.

They Hardy-Weinberg equation is:

p² + 2pq + q² = 1

p = dominant alleles frequency (A)

q = recessive alleles frequency (a)

p² = dominant homozygous genotype frequency (AA)

q² = recessive homozygous genotype frequency (aa)

2pq = heterozygous genotype frequency (Aa)

p² and 2pq = dominant phenotype frequency (A)

q² = recessive phenotype frequency (a)

Note: A or a is for example in which A represent the dominant allele while a represent the recessive allele.

Hardy Weinberg equation is presented below and describes that in a population the frequency of alleles ad genotypes will remain static or the same in the absence of evolutionary disturbances such as mutation, migration (gene flow), natural selection and with the population large and random mating

p² + 2pq + q²

where p represents the frequency of the dominant alleles

q represent the frequency of the recessive alleles

p² represent the frequency of the dominant homozygous genotype

q² represent the frequency of the recessive homozygous genotype

2pq represent the frequency of the heterozygous genotype

q² also represent the frequency of the recessive phenotype

(p² + 2pq) represent the frequency of the dominant phenotype
