Allele frequency refers to: The total number of alleles in an individual. The number of alleles in a dimorphic population. The proportion of an allele relative to the total number of alleles in a population. The number of alleles that can exist for a certain gene.

The proportion of an allele relative to the total number of alleles in a population.

Explanation:

The genic or allelic frequency refers to the proportion of each allele in a given locus of a specific population. If the population is under the Hardy-Weinberg equilibrium, the sum of the allelic frequencies always equals 1.

The allelic frequency is significant while analyzing the gene transition in the population. Also, genotypic frequencies are directly related to allelic frequencies, mathematically defining them.
