# What do the variables in the Hardy Weinberg equation represent frequency of the homozygous recessive genotype?

Contents

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

is the frequency of the recessive allele. ² is the frequency of individuals with the homozygous dominant genotype. 2 is the frequency of individuals with the heterozygous genotype. ² is the frequency of individuals with the homozygous recessive genotype.

## 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 do p and q represent in Hardy-Weinberg?

The Hardy-Weinberg equation is a mathematical equation that can be used to calculate the genetic variation of a population at equilibrium. … where p is the frequency of the “A” allele and q is the frequency of the “a” allele in the population.

## 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.

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

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.

1. The frequency of the recessive allele. …
2. The frequency of the dominant allele. …
3. The frequency of heterozygous individuals.

## What is the homozygous dominant genotype?

An organism with two dominant alleles for a trait is said to have a homozygous dominant genotype. Using the eye color example, this genotype is written BB. An organism with one dominant allele and one recessive allele is said to have a heterozygous genotype.

## 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.

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

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

## How is genotype frequency calculated?

The frequency of genotype Aa is determined by multiplying 2 times the frequency of A times the frequency of a. The frequency of aa is determined by squaring a. Try changing p and q to other values, ensuring only that p and q always equal 1.

Genotype Expected Frequency
aa or A2A2 q * q = q2

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

The frequency will remain the same. Homozygous recessive individuals selectively leaving a population is an example of: … What will happen to the frequency of the recessive allele for the HbS gene when there is an outbreak of malaria? The frequency will increase.
