## Which variable in the Hardy Weinberg equation represents the frequency of homozygous recessive phenotype?

The HardyWeinberg equations can be used for any population; the population does not need to be in equilibrium. is the frequency of the dominant allele. is the frequency of the recessive allele. ² is the frequency of individuals with the homozygous dominant genotype.

## What is the frequency of the recessive phenotype?

The recessive phenotype is controlled by the homozygous aa genotype. Therefore, the frequency of the dominant phenotype equals the sum of the frequencies of AA and Aa, and the recessive phenotype is simply the frequency of aa.

## What will happen to the frequency of the recessive allele?

The answer is the frequency of the recessive allele will increase.

## What is the phenotype frequency?

Relative phenotype frequency is the number of individuals in a population that have a specific observable trait or phenotype. … Relative genotype frequency and relative allele frequency are the most important measures of genetic variation.

## Why is the sum of p and q 1?

where p is the frequency of the “A” allele and q is the frequency of the “a” allele in the population. … In addition, the sum of the allele frequencies for all the alleles at the locus must be 1, so p + q = 1.

## Why is there a 2 in 2pq?

The term p2 represents the frequency of dominant homozygotes (AA) and the term q2 represents the frequency of recessive homozygotes (aa). p represents the allele frequency of allele A, and q represents the allele frequency of the allele a.
