All alleles have the same reproductive advantages (no natural selection)
|
Detailed explanation-1: -There are five basic Hardy-Weinberg assumptions: no mutation, random mating, no gene flow, infinite population size, and no selection. If the assumptions are not met for a gene, the population may evolve for that gene (the gene’s allele frequencies may change).
Detailed explanation-2: -In order for a population to exist in Hardy-Weinberg equilibrium, natural selection must not occur. Natural selection is an important factor in biological evolution.
Detailed explanation-3: -Occurrence of natural selection and small size in population do not meet the criteria for a population to reach Hardy-Weinberg equilibrium.
Detailed explanation-4: -Hardy-Weinberg equilibrium requires no immigration or emigration, a large population, random mating, and no spontaneous mutations (all of which are virtually unavoidable in nature). Natural selection would violate these conditions.
