# Frequent question: What is the frequency of the homozygous dominant allele?

Contents

According to the Hardy-Weinberg principle, the square root of the homozygous genotype frequency is equal to the allele frequency. The dominant allele frequency is 0.7.

## What is the frequency of homozygous dominant?

The frequency of homozygous dominant plants (p2) is (0.6)2 = 0.36. Out of 100 individuals, there are 36 homozygous dominant (YY) plants. The frequency of heterozygous plants (2pq) is 2(0.6)(0.4) = 0.48. Therefore, 48 out of 100 plants are heterozygous yellow (Yy).

## How do you find the homozygous allele frequency?

1 = p2 + 2pq + q2

The term p2 represents the frequency of the homozygous dominant genotype. The other term, q2, represents the frequency of the homozygous recessive genotype.

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

Calculate the percentage of individuals homozygous for the dominant allele. 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 are the alleles for homozygous dominant?

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 frequency of homozygous dominant?

Use the Hardy-Weinberg equilibrium.

1. Alleles: p+q=1.
2. p=frequency of the dominant allele. …
3. p2=frequency of homozygous dominant genotype. …
4. In your scenario, the dominant phenotype has a frequency of 0.19 .
5. This is misleading, since both the p2 and 2pq terms represent the dominant phenotype. …
6. If q2=0.81 , we can determine q .

## What is the frequency of a dominant allele?

The frequency of the dominant allele in the population. Answer: The frequency of the dominant (normal) allele in the population (p) is simply 1 – 0.02 = 0.98 (or 98%). The percentage of heterozygous individuals (carriers) in the population.

## What is an example of allele frequency?

Example: assuming that in a human population, there are 100 individuals. Since each of them would have two alleles for a particular character (one allele inherited from the father, the other allele from the mother), the total number of genes in this population is 200 (=100 x 2). … Variant: allelic frequency.

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

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