## What is the frequency of the homozygous recessive genotype?

We know that the frequency of the recessive homozygote genotype is q2 and equal to 0.09. Thus, p = 1 – q ∴ p = 1 – 0.30 = 0.70 ∴The homozygote dominants are represented by p2 = (0.70)2 = 0.49 or 49% Page 2 4.

## What variable in the Hardy-Weinberg equations represents the frequency of the recessive phenotype?

What percentage of the population is heterozygous? Explanation: Using the Hardy-Weinberg equilibrium equations, you can determine the answer. The value of gives us the frequency of the dominant allele, while the value of gives us the frequency of the recessive allele.

## What part of the Hardy-Weinberg formula represents the frequency of the homozygous recessive genotype?

Explanation: In the Hardy-Weinberg equilibrium equation ( p2+2pq+q2=1 ), the term 2pq represents the genotype frequency of heterozygotes (Aa) in a population in equilibrium. The term p2 represents the frequency of dominant homozygotes (AA) and the term q2 represents the frequency of recessive homozygotes (aa).

## How do you find the frequency of homozygous recessive?

To determine q, which is the frequency of the recessive allele in the population, simply take the square root of q2 which works out to be 0.632 (i.e. 0.632 x 0.632 = 0.4). So, q = 0.63.

## What is the frequency of the homozygous recessive genotype BB?

For example: ‘The frequency of genotype Bb in the population is 0.42.

## What is the Hardy Weinberg symbol for the frequency of the recessive allele?

² is the frequency of individuals with the homozygous recessive genotype.

## Is P or Q recessive?

In the simplest system, with two alleles of the same locus (e.g. A,a), we use the symbol p to represent the frequency of the dominant allele within the population, and q for the frequency of the recessive allele.

## What does the Q represent in the Hardy Weinberg equation?

The Hardy-Weinberg Equation

p = the frequency of the dominant allele in a population. q = the frequency of the recessive allele in a population.

## How do you find the genotype frequency of Hardy-Weinberg?

To calculate the allelic frequencies we simply divide the number of S or F alleles by the total number of alleles: 94/128 = 0.734 = p = frequency of the S allele, and 34/128 = 0.266 = q = frequency of the F allele.
