The Formula P2 + 2pq + Q2 = 1 Is

Question

The formula p2 + 2pq + q2 = 1 is associated with which of the following?
A) Calculations of heterozygosity
B) Hardy-Weinberg equilibrium
C) Calculations of recombination frequencies
D) Degrees of freedom

Accepted Answer

The formula p2 + 2pq + q2 = 1 is a mathematical representation of the Hardy-Weinberg equilibrium, which describes the genetic equilibrium in a population that is not undergoing evolutionary change. This equation relates the frequencies of different genotypes to the frequency of alleles in a population, assuming certain conditions are met (such as random mating, no mutation, no migration, etc.). This equation can be used to calculate the expected frequencies of different genotypes in a population, given the frequency of alleles, or to test whether a population is in Hardy-Weinberg equilibrium based on observed genotype frequencies.
