Question

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

Answer 1

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.

Answer 2

Step-by-step explanation:

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
