Question

State Hardy-Weinberg’s principle.

Short/Brief Note
Advertisements

Solution

All the genes and their alleles found in an interbreeding population is called gene pool. Normally, the alleles tend to maintain an equilibrium with reference to one another oyer the generation irrespective of the phenotypic expression. It is called genetic equilibrium. A change in relative frequency of alleles brings about evolution.
