Summary Introduction
Introduction:
The population genetics depends on the close relationship of genotype and allele frequencies. Genotype frequency can be calculated by the number of individuals with their genotype that is divided by entire number of the population. According to Hardy-Weinberg law, frequencies of allele and gene cannot change from one generation to another.
