Q. …A… is a binomial expression of $(p + q)^{2}$. When frequency measured, differs from the expected values, the difference indicates the extent of …B… Choose the option for A and B to complete the given NCERT statement
A) A$- p^{2} + 2pq + q^{2} = 1$; B-evolutionary change
B) A$- p^{2} + 2pq + q^{2} + q^{2} = 1$; B-genetic change
C) A$- p^{2} + 2pq + q^{2} \geq 1$; B-genetic change
D) A$- p^{2} + 2pq + q^{2} \leq 1$; B-evolutionary change
Explanation
$A - p^{2} + 2pq + q^{2} = 1$; B = Evolutionary charge
