How to Use the Calculator

  1. Enter the frequency of allele A (p) in the first input field. This should be a number between 0 and 1.
  2. Enter the frequency of allele a (q) in the second input field. This should also be a number between 0 and 1.
  3. Click the "Calculate" button to compute the heterozygous frequency (2pq).
  4. The result will be displayed in the result field.

Hardy-Weinberg Principle

The Hardy-Weinberg principle is a fundamental concept in population genetics that describes how allele and genotype frequencies in a population will remain constant from generation to generation in the absence of other evolutionary influences. The principle is based on several assumptions, including no mutation, random mating, no migration, no natural selection, and a large population size.

The formula for calculating the frequency of heterozygotes (Aa) in a population is 2pq, where p is the frequency of allele A and q is the frequency of allele a.
