# Why is the Hardy-Weinberg equation important?

Jun 15, 2016

Hardy Weinberg law gives the idea when there is no evolution or we can say that population remains in equilibrium.

P + Q = 1
${P}^{2}$ + 2PQ + ${Q}^{2}$ =1
the equation also describes about the allelic frequecies.

The equation is a model used to determine the allele and genotype amounts in a population.

#### Explanation:

The theory states that if a population meet certain criteria, evolution will not occur. These includes:

• No mutation
• No migration
• Large Population
• Random mating
• No natural selection
