Equations used to predict:
- The allele and genotype relative frequencies in a stable population
- Whether a population is stable or evolving
Assume the population is stable, let
Examples
In a Hardy-Weinberg population, 4% have cystic fibrosis caused by the recessive allele. What is the percent of carriers (heterozygous individuals) of this disease in this population?
We observe 60% AA individuals and 40% aa individuals. Is the population stable?
Because there is no Aa individual, the Hardy-Weinberg equation is not satisfied, so the population is not stable.
