In population genetics, the Hardy–Weinberg principle, also known as the Hardy–Weinberg equilibrium, model, theorem, or law, states that allele and genotype frequencies in a population will remain constant from generation to generation in the absence of other evolutionary influences.

This calculator demonstrates the application of the Hardy-Weinberg equations to loci with more than two alleles. Visit the genetic drift and selection illustration for more on the Hardy-Weinberg Equilibrium. Update the values by changing the allele frequency in the blue box below the graph.

Nov 23, 2024 · The Hardy-Weinberg principle states that a population’s allele and genotype frequencies will remain constant in the absence of evolutionary mechanisms. Ultimately, the Hardy-Weinberg principle models a population without evolution under the following conditions: no mutations; no immigration/emigration; no natural selection; no sexual selection

The Hardy-Weinberg Equilibrium Calculator bridges the gap between theory and application, enabling users to quickly compute allele and genotype frequencies. By simplifying complex genetic equations, the tool is ideal for:

In this guide I will describe what the Hardy-Weinberg principle is and the assumptions behind it. Additionally, by using examples, I will demonstrate how to use the Hardy-Weinberg equations to calculation allele and genotype frequencies.

The Hardy-Weinberg theorem characterizes the distributions of genotype frequencies in populations that are not evolving, and is thus the fundamental null model for population genetics.

Let's take a look at some graphs of this to make it a little easier to see. For values of p from 0 to 1, in intervals of 0.1, here's what we get: p+q=1, so p=1-q and q=1-p. Red represents the frequency of the AA or A1A1 genotype, green is the Aa or A1A2 genotype, and blue is …

This online calculator can be used to determine the allele frequencies and to calculate, using the Hardy-Weinberg equation, the expected number of common homozygotes, heterozygotes and rare homozygotes, from observed genotype counts for a gene with two alleles.

The Hardy-Weinberg Principle is defined as a fundamental concept in population genetics and evolutionary biology. It explains how allele and genotype frequencies are interrelated, allowing genetic variation to persist over successive generations.

Implements several graphics for exploring the equilibrium status of a large set of bi-allelic markers: ternary plots with acceptance regions, log-ratio plots and Q-Q plots. The functionality of the package is explained in detail in a related paper (Graffelman, 2015). GPL Version 2 or later.
