## How does Hardy-Weinberg calculate allele frequencies?

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.

## How does the frequency of alleles change from generation to generation?

allele frequencies in **a population will not change from generation to generation**. if the allele frequencies in a population with two alleles at a locus are p and q, then the expected genotype frequencies are p^{2}, 2pq, and q^{2}.

## How do you know if something is in Hardy-Weinberg equilibrium?

To know if a population is in Hardy-Weinberg Equilibrium scientists **have to observe at least two generations**. If the allele frequencies are the same for both generations then the population is in Hardy-Weinberg Equilibrium.

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

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

## How do you solve for allele frequencies?

**Allele Frequency**

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

## What is the difference between allelic and genotypic frequencies?

Relative genotype frequency is the **percentage of individuals** in a population that have a specific genotype. … Relative allele frequency is the percentage of all copies of a certain gene in a population that carry a specific allele. This is an accurate measurement of the amount of genetic variation in a population.

## Which generation showed the greatest frequency of having one of each allele?

Answer: The answer is: **The first generation**. Explanation: In genetics the allelic frequency or gene frequency is the proportion observed of a specific allele with respect to the set of those who can occupy a given locus in the population.

## How do you find the frequency of a recessive allele?

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).
