E
Random Mating occurs
Verified step by step guidance1
Understand the Hardy-Weinberg principle: It describes a model where allele and genotype frequencies in a population remain constant from generation to generation in the absence of evolutionary influences.
Identify the assumptions of the Hardy-Weinberg equilibrium: These include no mutation, no selection, no migration, infinitely large population size, and random mating.
Examine each option provided in the problem: 'No Selection', 'No Migration', 'Infinitely large population', and 'Random Mating occurs' are all assumptions of the Hardy-Weinberg equilibrium.
Consider the option 'New Alleles': The introduction of new alleles typically occurs through mutation, which is not an assumption of the Hardy-Weinberg equilibrium.
Conclude that 'New Alleles' is the correct answer as it is not an assumption made when using the Hardy-Weinberg formula.
