Which of the following statements is true regarding the conditions necessary for Hardy-Weinberg equilibrium in a population?
A
The population must have a high mutation rate.
B
The population must have non-random mating.
C
The population must be infinitely large.
D
The population must experience natural selection.
Verified step by step guidance1
Understand the concept of Hardy-Weinberg equilibrium: It is a principle that describes a stable genetic state in a population where allele and genotype frequencies remain constant from generation to generation, provided that certain conditions are met.
Identify the conditions necessary for Hardy-Weinberg equilibrium: These include a large population size, random mating, no mutation, no migration, and no natural selection.
Evaluate the given statements against these conditions: The statement 'The population must be infinitely large' aligns with the condition of a large population size, which minimizes the effects of genetic drift.
Consider why the other statements do not fit: A high mutation rate would introduce new alleles, disrupting equilibrium. Non-random mating would change genotype frequencies. Natural selection would favor certain alleles, altering allele frequencies.
Conclude that the correct condition for Hardy-Weinberg equilibrium from the given options is that the population must be infinitely large, as it ensures genetic stability by reducing the impact of random fluctuations.
