Detailed explanation-1: -Allele frequency, or gene frequency, is the relative frequency of an allele (variant of a gene) at a particular locus in a population, expressed as a fraction or percentage. Specifically, it is the fraction of all chromosomes in the population that carry that allele over the total population or sample size.

Detailed explanation-2: -These variations code for different traits associated with that characteristic. The allele frequency (or gene frequency) is the rate at which a specific allele exists within a population. Allele frequencies can be expressed as a decimal or as a percent and always add up to 1, or 100 percent, of the total population.

Detailed explanation-3: -Relative allele frequency is the percentage of all copies of a certain gene in a population that carry a specific allele. This is an accurate measurement of the amount of genetic variation in a population.

Detailed explanation-4: -It is measured by the number of reproducers per generation, N, which is about one third of the population census for human populations. The smaller is N, the greater is the genetic variation among populations, estimated by variance measurements, and the smaller that within populations.
