If `p^(2)+2pq+q^(2)=1`. Explain this algebraic equation on the basis of Hardy Weinberg's principle.

Explanation

`p^(2)+2pq+q^(2)=1`. This is a binomial expansion of (p+q)2. When frequency measuring differs from excepted values, the difference (direction) indicates the extent of evolutionary change. Disturbance in genes equilibrium, or Hardy-Weinberg's equilibrium, i.e., change of frequency of alleles in a population would then he interpreted as resulting in evolution.
