# How do you calculate the percentage of individuals homozygous for the dominant allele?

Contents

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 is the percentage of homozygous individual?

(i) The percentage of homozygous dominant individuals is 25%.

## What is the percentage of homozygous and heterozygous?

One parent is Aa and the other is aa: Their child has a 50 percent chance of being Aa (heterozygous) and a 50 percent chance of being aa (homozygous). One parent is Aa and the other is AA: Their child has a 50 percent chance of being AA (homozygous) and a 50 percent chance of being Aa (heterozygous).

## What is the percentage of homozygous and heterozygous population?

50% are homozygous and 50% heterozygous out of the homozygous population 25% is homozygous dominant and 25% homozygous recessive. The genotypic ratio is 1 : 2 : 1 25% homozygous dominant 50 % helerozygous and 25% homozygous recessive.

## How do you calculate heterozygous frequency?

The frequency of heterozygous individuals. Answer: The frequency of heterozygous individuals is equal to 2pq. In this case, 2pq equals 0.32, which means that the frequency of individuals heterozygous for this gene is equal to 32% (i.e. 2 (0.8)(0.2) = 0.32).

## How do you calculate allele and genotype frequencies?

The frequency of genotype AA is determined by squaring the allele frequency A. 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.

Genotype Expected Frequency
Aa or A1A2 pq + pq (or 2pq)
aa or A2A2 q * q = q2

## How do you calculate allele frequency from phenotype?

Allele Frequency

1. Allele frequency is most commonly calculated using the Hardy-Weinberg equation, which describes the relationship between two alleles within a population. …
2. To find the number of alleles in a given population, you must look at all the phenotypes present. …
3. 1 = p2 + 2pq + q2

## What will be the total percentage of homozygous recessive plant?

The total percent of homozygous recessive plant in F2 generation is 1%.

## How do you determine if a person is homozygous or heterozygous?

Because an organism has two sets of chromosomes, it usually only has two options to choose from when determining phenotype. If an organism has identical genes on both chromosomes, it is said to be homozygous. If the organism has two different alleles of the gene it is said to be heterozygous.
