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.

## How do you find the frequency of a dominant phenotype?

**1 Answer**

- 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 .
- q=√q2=√0.81=0.9.

## How do you calculate allele frequencies?

Allele frequency refers to how common an allele is in a population. It is determined by **counting how many times the allele appears in the population then dividing by the total number of copies of the gene**.

## Is allele frequency related to dominance?

The **rate of increase in frequency of the favored allele will** depend on whether the allele is dominant or recessive. … In general, a new favored dominant allele will increase rapidly in the population, because even the heterozygous individuals have the “improved” phenotype (produce more surviving offspring).

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

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

## What is the frequency of heterozygotes?

and the frequency of heterozygotes is **2pq = 2 x 99/100 x 1/100 = 2/100**; Note that there are a lot of heterozygotes: 1/50, two hundred times more than there are individuals suffering from the condition. . For a rare disease, p is very little different from 1, and the frequency of the heterozygotes = 2q.

## 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 is the phenotype frequency?

Relative phenotype frequency is **the number of individuals in a population that have a specific observable trait or phenotype**. … Relative genotype frequency and relative allele frequency are the most important measures of genetic variation.

## How do you find the frequency of heterozygotes in a population?

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).

## What is major allele frequency?

In addition, the major allele, by definition, could have a frequency of **50.5%**, in which case, although it is more frequent, it is only more frequent by 0.5%.
