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 (p^{2}) 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 = p ^{2} + 2pq + q^{2}**

The term p^{2} represents the frequency of the homozygous dominant genotype. The other term, q^{2}, 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.**

- Alleles: p+q=1.
- p=frequency of the dominant allele. …
- p2=frequency of homozygous dominant genotype. …
- In your scenario, the dominant phenotype has a frequency of 0.19 .
- This is misleading, since both the p2 and 2pq terms represent the dominant phenotype. …
- 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**.
