# 7 Best Free Online Allele Frequency Calculator Websites

Here is a list of the **best free online Allele Frequency Calculator websites**. An allele is a gene variant. Every gene has two variants making it 2 alleles per chromosome. The alleles are inherited from the parent. One allele always comes from the mother and the one from the father. Allele frequency describes how often a particular allele can be found in a population. With the allele frequency, you can calculate the chances that you and your partner are carriers of a genetic disease that may affect your children. Before moving forward, here are some useful definitions that one should know:

- p – frequency of the wild (healthy) allele
- q – frequency of the mutant (sick) allele
- p² – frequency of people without the disease in the population (2 healthy alleles)
- q² – frequency of people with the disease in the population (2 mutant alleles)
- 2pq – frequency of people without the disease in the population (1 mutant, 1 healthy allele)

An Allele Frequency Calculator allows you to calculate the chances of being a carrier of a certain genetic trait. To calculate allele frequency, you need to know the frequency of the disease either in percentage or proportion. Alternatively, you must know the observed values of the genotypes. There are two types of calculators in this post. You can go through the post and check them out in detail.

## My Favorite Online Allele Frequency Calculator

**OmniCalculator** is my favorite website on this list to calculate allele frequency. It is quite simple to use and gives you the allele frequency from a proportion or percentage of the population.

You can also check out our lists of the best free 3D Anatomy Software for Windows, Health Symptom Checker Services, and Pregnancy Calculator Online Websites.

## OmniCalculator.com

**OmniCalculator.com** has a free online allele frequency calculator. This calculator takes the Frequency of the disease in the population in proportion or percentage. From that, it determines the Heathy (p) and Mutant (q) allele frequency. Along with the allele frequency, it also shows the carrier frequency. This implies how many people have mutant alleles out of a group of people. Calculations also include People with two healthy alleles (p²), people with two mutant alleles (q²), and People with one healthy, and one mutant allele (2pq).

### How to calculate Allele Frequency with OmniCalculator?

- Go to this calculator using the link given below.
- Select either the Percentage or Proportion option as per your requirement.
- Then enter the occurrence of the disease as per your selection.
- This shows the Healthy and Mutant Allele Frequency.

### Highlights:

- This calculator can calculate allele frequency from
**proportion**or**percentage**. - It shows the
**Heathy (p)**allele frequency and**Mutant (q)**allele frequency. - It also calculates the
**carrier frequency**of the mutant allele along with**p²**,**q²**, and**2pq**.

## Perinatology.com

**Perinatology.com** offers a free online allele frequency calculator. This calculator uses the Hardy-Weinberg equation to estimate the frequency of the carrier state (2pq) for an autosomal recessive trait. All you have to do is add the population that has recessive traits either in percentage or in proportion. With that, this calculator gives you the frequency of wild-type allele (p), frequency of a mutant allele (q), and frequency of people without the disease in the population (2pq).
