The rodent population would not be in Hardy-Weinberg equilibrium if there are factors such as mutations introducing new alleles, natural selection favoring certain traits, genetic drift due to small population size, or gene flow from neighboring populations affecting allele frequencies. Additionally, if there are mating preferences or non-random mating occurring within the population, this could also disrupt the equilibrium. These factors lead to changes in allele frequencies over generations, deviating from the expected proportions under Hardy-Weinberg conditions.
Allele frequency is stable
Yes it is obtainable in plant population
Mutations introduce new genetic variation into a population, which can disrupt the balance of allele frequencies required for the Hardy-Weinberg equilibrium. If a mutation increases the frequency of a particular allele, it can lead to deviations from the expected genotype frequencies under the Hardy-Weinberg equilibrium.
No disruptive circumstances must be present in random mating in a population for Hardy-Weinberg equilibrium to occur. Mating must happen randomly. No allele can give an advantage
Conditions for Hardy-Weinberg equilibrium include a large population size, random mating, no mutations, no natural selection, and no gene flow (migration). Therefore, the absence of these conditions—such as small population size, non-random mating, mutations, selection pressures, or migration—are not conditions for Hardy-Weinberg equilibrium. These factors can lead to changes in allele frequencies and disrupt genetic equilibrium.
Hardy-Weinberg equilibrium
A large population residing on an isolated island is more likely to reach Hardy-Weinberg equilibrium.
Allele frequency is stable
Yes it is obtainable in plant population
If a new allele appears in a population, the Hardy-Weinberg formula cannot be used. This is because there is now no equilibrium.
Mutation is the factor that does not take a population out of Hardy-Weinberg equilibrium. The other factors that can disrupt equilibrium are natural selection, genetic drift, gene flow, and non-random mating.

When an organism is in Hardy-Weinberg equilibrium there is no evolution. There is no mutation, mating is random and thus no natural selection. Naturally, outside of labs this condition is never seen.

One condition for Hardy-Weinberg equilibrium is a large population size. This ensures that genetic drift, which is the random change in allele frequencies, has minimal effect on the gene pool.
