How do you calculate an allele frequency?

Allele frequency is a measure of the relative frequency of an allele on a genetic locus in a population. Usually it is expressed as a proportion or a percentage. In population genetics, allele frequencies show the genetic diversity of a species population or equivalently the richness of its gene pool.

Similarly one may ask, what affects gene frequency?

Clearly, allele frequencies can change over time within a single population, and frequently differ between populations. The following discussion deals with the most important factors affecting allele frequencies: Genetic Isolation, Migration (gene flow), Mutation, Natural Selection, Artificial Selection, and Chance.

What is the Hardy Weinberg equation used for?

The HardyWeinberg principle, also known as the HardyWeinberg equilibrium, model, theorem, or law, states that allele and genotype frequencies in a population will remain constant from generation to generation in the absence of other evolutionary influences.
