Expert Solution

Step 1

Hardy Weinberg’s principle is the mathematical representation of population analysis which calculates the genetic variation possible in a population at equilibrium by calculating its allelic and genotypic frequencies.This principle only stands true in certain conditions that include- No mutation, no emigration/immigration, no natural selection, no evolution, no gene flow etcetera. Although all these conditions cannot be satisfied by a population still it is a useful analysis method. Hardy Weinberg equilibrium states that the genetic variation in a population will remain consistent with respect to genotype and allele frequency, from one generation to the next in the absence of disturbing circumstances
