BIOLOGY & AGRICULTURE CALCULATOR
Hardy Weinberg Extended
A precise tool.
What is the Hardy Weinberg Extended & How does it work?
The Hardy-Weinberg principle is a fundamental concept in population genetics that describes how the frequencies of alleles and genotypes in a population remain constant from generation to generation under certain conditions. These conditions include no mutation, no migration, random mating, no selection, large population size, and no genetic drift.
p^2 + 2pq + q^2 = 1
p = frequency of the dominant allele, q = frequency of the recessive allele, p^2 = frequency of the homozygous dominant genotype, 2pq = frequency of the heterozygous genotype, q^2 = frequency of the homozygous recessive genotype
The Hardy-Weinberg calculator allows you to input the allele frequencies and calculate the expected genotype frequencies in a population.

Frequently Asked Questions
What is the Hardy-Weinberg principle?
It’s a concept in population genetics that predicts genotype frequencies in a stable population.
How do I use this calculator?
Input the allele frequencies or genotype counts to calculate the missing values using Hardy-Weinberg equations.
What conditions must be met for Hardy-Weinberg equilibrium?
No mutation, no migration, random mating, no selection, large population size, and no genetic drift.
Can this calculator handle populations with more than two alleles?
This specific calculator is designed for two alleles. For more complex scenarios, a different tool would be needed.
What does p^2 represent in the Hardy-Weinberg equation?
p^2 represents the frequency of the homozygous dominant genotype in the population.
How do I interpret the results from this calculator?
The results show the expected frequencies of genotypes based on the Hardy-Weinberg equilibrium.
Is this calculator suitable for agricultural studies?
Yes, it can be used to understand genetic diversity and breeding programs in agriculture.
