## How do you calculate allele frequencies?

An allele frequency is calculated by **dividing the number of times the allele of interest is observed in a population by the total number of copies of all the alleles at that particular genetic locus in the population**. Allele frequencies can be represented as a decimal, a percentage, or a fraction.

## 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 A_{1}A_{2} |
pq + pq (or 2pq) |

aa or A_{2}A_{2} |
q * q = q^{2} |

## How do you find the Hardy Weinberg phenotypic frequency?

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. Answer: Since 2pq equals the frequency of heterozygotes or carriers, then the equation will be as follows: 2pq = (2)(.

## 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.

## Is migration a gene flow?

Gene flow is also called gene migration. Gene flow is **the transfer of genetic material from one population to another**. Gene flow can take place between two populations of the same species through migration, and is mediated by reproduction and vertical gene transfer from parent to offspring.

## How many alleles are in a gene?

An allele is one of two or more versions of a gene. An individual inherits **two alleles** for each gene, one from each parent. If the two alleles are the same, the individual is homozygous for that gene.

## How do you find frequency?

To calculate frequency, **divide the number of times the event occurs by the length of time**. Example: Anna divides the number of website clicks (236) by the length of time (one hour, or 60 minutes).
