Which of the following represents the Hardy Weinberg equation?(a) p^2 + q^2 = 1(b) p^2 + 2pq + q^2 = 1(c) p^2 + q^2 = 0(d) (p^2 + q^2)^2 = 1This question was posed to me in final exam.The query is from Hardy-Weinberg Principle-2 in division Evolution of Biology – Class 12

Answer»

The correct option is (b) P^2 + 2pq + Q^2 = 1

To EXPLAIN: The Hardy Weinberg EQUATION is p^2 + 2pq + q^2 = 1. Here, p^2 denotes the allele of AA and q^2 denotes the allele aa. This shows that p, q,and A, a are related in multiplication. So, 2pq represent Aa.
