Q. Which of the following defines Hardy –Weinberg law?
A) $p^{2} + 2pq + q^{2} = 1$
B) $p^{2} + 2pq + q^{2} = 1$
C) $p^{2} + 2pq + q^{2} = 0$
D) $q^{2} + p^{2} + 2pq = 0$
Explanation
Hardy Weinberg equilibrium describes that under certain conditions of stability allelic frequencies remain constant from generation to generation in sexually reproducing organisms. The Hardy –Weinberg law uses the binomial expression $p^{2} + 2pq + q^{2} = 1$to calculate genotype and allele frequencies of a population.
