## 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 q ^{2}** 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.
