<h3>What is Allelic frequency?</h3>

The allelic frequency may be defined as the sum total of all the alleles of a gene in a population. It represents the overall genetic diversity within a population.

The allelic frequency is calculated by the formula when the genotypes are given in number. It is as follows:

2 × Number of Purebred dominant + Number of heterozygous/ 2× Total number of individuals in a population.

∴ Allelic frequency of dominant allele = 2 × 50 + 34/ 2× 100 = 134/200 = 0.67.

The allelic frequency of the Dominant allele is 0.67 while the allelic frequency of the recessive allele is 0.33.

Therefore, it is well described above.
