Hardy-Weinberg Equilibrium Calculator

Formula

To calculate the Hardy-Weinberg equilibrium (Hwe) value:

\[ Hwe = \left(2 \times p \times q\right)^2 \]

Where:

\(Hwe\) is the Hardy-Weinberg equilibrium value
\(p\) is the frequency of the first allele in the population
\(q\) is the frequency of the second allele in the population

What is Hardy-Weinberg Equilibrium?

Hardy-Weinberg equilibrium is a principle used in population genetics to describe the genetic variation in a population under ideal conditions. It states that allele and genotype frequencies in a population will remain constant from generation to generation in the absence of evolutionary influences. These influences include genetic drift, mutation, migration, and natural selection. The equilibrium provides a baseline to study the genetic structure of populations and to determine if and how a population is evolving.

Example Calculation

Let's assume the following values:

Frequency of the first allele (\(p\)) = 0.4
Frequency of the second allele (\(q\)) = 0.6

Using the formula:

\[ Hwe = \left(2 \times 0.4 \times 0.6\right)^2 = \left(2 \times 0.24\right)^2 = 0.48^2 = 0.2304 \]

The Hardy-Weinberg Equilibrium Value is 0.2304.
