Info - Hardy Weinberg

Problem Solver

(calculator)

The Hardy Weinberg problem solver calculates allele frequencies from observed genotype counts for a single gene in a population, as well as the genotype counts which would be expected under Hardy-Weinberg assumptions.

The inbreeding co-efficient (F value) is also calculated

Parameters entered are:

  • Observed AA count
  • Observed Aa count
  • Observed aa count

More information on Hardy Weinberg equilibrium can be found here

For example:

Test Yourself

(problem generator)

Random values for observed genotype counts for a single gene in a population (AA, Aa and aa) are generated and presented.

Based on these observed genotype counts, your aim is to correctly calculate:

  • the frequence of Alleles "A" and "a" present in the population for the gene
  • the inbreeding co-efficient (F value)
  • the expected genotype counts if the population was at Hardy Weinberg equilibrium
