A) \[{{p}^{2}}+\text{ }2pq+\text{ }{{q}^{2}}=\text{ }1\]
B) \[{{p}^{2}}+\text{ }2pq+\text{ }{{q}^{2}}=\text{ }1\]
C) \[{{p}^{2}}+\text{ }2pq+\text{ }{{q}^{2}}=\text{ }0\]
D) \[{{q}^{2}}+\text{ }{{p}^{2}}+\text{ }2pq=\text{ }0\]
Correct Answer: A
Solution :
The Hardy-Weinberg law is the fundamental law of population genetics, which provides the basis of studying Mendelian populations. The Hardy-Weinberg law states that the gene and genotypic frequencies in a Mendelian population remain constant generation after generation if there is no selection, mutation, migration or random drift. It uses the binomial expression \[{{p}^{2}}+2pq+{{q}^{2}}\] to calculate the genotypic and allele frequencies of a population.
