population size decreases
A population is in genetic equilibrium when allele frequencies remain constant over generations, indicating that there is no evolution occurring. This suggests that the population is not experiencing any genetic drift, gene flow, mutations, or natural selection.
Random changes in allele frequency are due to genetic drift.
No, stable allele frequencies do not prevent microevolution. Microevolution involves changes in allele frequencies within a population over time, even if those frequencies are stable for a period. Evolution can still occur through mechanisms such as genetic drift, selection, and gene flow, even if allele frequencies are temporarily stable.
Genetic equilibrium is a state in which the allele frequencies in a population remain constant and do not change over time. This means that the population is not evolving and there is no change in the genetic makeup of the population.

Allele frequencies are used to study genetic variation within a population. They can provide information about the genetic diversity, evolution, and potential for certain traits or diseases in a population. By tracking changes in allele frequencies over time, researchers can gain insights into how populations evolve and adapt to their environments.
Answer this question… Genetic drift
Random changes in allele frequency are due to genetic drift.
No, stable allele frequencies do not prevent microevolution. Microevolution involves changes in allele frequencies within a population over time, even if those frequencies are stable for a period.

Evolution; the change in allele frequencies over time in a population of organisms.
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.
If there is a large amount of genetic drift :)
The type of equilibrium where allele frequencies do not change is called Hardy-Weinberg equilibrium. This equilibrium occurs in an idealized population where certain assumptions are met, such as random mating, no mutation, no migration, no natural selection, and a large population size. In Hardy-Weinberg equilibrium, the genotype frequencies can be predicted using the allele frequencies.
Allele frequencies in a population refer to the proportion of each allele for a given gene among all alleles at that locus. Since all possible alleles at a locus contribute to the genetic makeup of that population, the sum of their frequencies must equal one, representing the entire genetic pool for that gene. This ensures that the distribution of alleles reflects the entirety of genetic variation available for that trait within the population.
Yes, allele frequencies are more likely to remain stable in large populations due to the effects of genetic drift being more pronounced in small populations. In small populations, random events can lead to significant changes in allele frequencies, whereas in large populations, genetic drift has less impact and allele frequencies are more likely to remain stable over time.
