Name the law that states that the sum of allelic frequencies in a population remains constant. What are the five factors that influence these values ?

Text Solution

Verified by Experts

It is Hardy-Weinberg law or Equilibrium that states that sum of allele frequencies in a population remains constant so that under certain conditions there is hereditary conservation of genes. There are five factors, called evolutionary agents, which influence the allele frequencies. These agents are: Mutations, Recombina-tion of genes, Gene flow, Genetic drift and Natural selection
