It is a comparative recurrence of an allele on a genetic locus in a population.
It is expressed in terms of percentage, decimal or fraction.
The variety of a species population genetics is given by Allele frequency.
It represents the incidence of a gene variant in a population.
It is calculated by dividing the number of times the allele of interest is observed in a population by the total number of copies of all the alleles at that particular genetic locus in the population.
Allele frequency is a reflection of genetic diversity.
