State the Hardy-Weinberg principle.

 Question:

 State the Hardy-Weinberg principle.

Explanation:

The Hardy-Weinberg principle states that in a large population not affected by the evolutionary processes such as mutation, selection or migration, the allele frequencies and the genotype frequencies are constant from one generation to the other. The principle can be explained by the simple equation: 

(p+q)2 = p2 +q2 + 2pq = 1 

Where, 

p = frequency of allele  

q = frequency of allele  

p2 = frequency of individual 

q2 = frequency of individual  

2pq = frequency of individual.
