How to determine if a population is in genetic equilibrium? The Hardy Weinberg Equilibrium Calculator helps you figure this out. Just enter values into the calculator, one can find out if the population follows the Hardy-Weinberg principle.
What is Hardy-Weinberg Equilibrium?
The Hardy-Weinberg Equilibrium is a principle in genetics. It states that allele and genotype frequencies in a population remain constant from generation to generation, given certain conditions. This equilibrium helps scientists understand genetic variation in populations.

Frequency of rare homozygous individuals |
How to Calculate Hardy-Weinberg Equilibrium
Follow these steps to calculate:
Step 1: Calculate the total population.
Total = Common Homozygotes + Heterozygotes + Rare Homozygotes
Step 2: Calculate the frequency of allele p.
Step 3: Calculate the frequency of allele q.
Step 4: Calculate expected frequencies:
Expected Common Homozygotes = Total
Expected Heterozygotes = Total
Expected Rare Homozygotes = Total
Example Solved
Step 1:
Total = 100 + 50 + 30 = 180
Step 2:
Step 3:
Step 4:
Expected Common Homozygotes = 180
Expected Heterozygotes = 180
Expected Rare Homozygotes = 180
