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.
Allele frequency is a term of population genetics that is used in characterizing the genetic diversity of a species population, or equivalently the richness of its gene pool. Allele frequency is defined as follows: ...

Allele frequency
Often called gene frequency. A measure of how common an allele is in a population; the proportion of all alleles at one gene locus that are of one specific type in a population.
If databases of allele frequency for different loci can be shown to be independently inherited by appropriate statistical tests, the probability for the combined genotype can be determined by the multiplication (product rule).

The final result of this random change in allele frequency is that the population eventually drifts to p=1 or p=0. After this point, no further change is possible; the population has become homozygous.

Changes in allele frequency that result because the genes appearing in offspring are not a perfectly representative sampling of the parental genes. (eg. in small populations). See also founder effect.
