What conditions would have to exist for the gene frequencies to stay the same?

Keeping this in consideration, what conditions must exist for frequencies to remain stable over multiple generations?

Five conditions are required in order for a population to remain at Hardy-Weinberg equilibrium:

• A large breeding population.
• Random mating.
• No change in allelic frequency due to mutation.
• No immigration or emigration.
• No natural selection.

Furthermore, when the frequency of alleles for a gene is constant over time that gene is said to be in genetic? The Hardy-Weinberg equilibrium is a principle stating that the genetic variation in a population will remain constant from one generation to the next in the absence of disturbing factors.

Beside this, what are the conditions necessary for a population to stay in Hardy Weinberg equilibrium?

The conditions to maintain the Hardy-Weinberg equilibrium are: no mutation, no gene flow, large population size, random mating, and no natural selection. The Hardy-Weinberg equilibrium can be disrupted by deviations from any of its five main underlying conditions.

Is it possible for genotypic frequencies to change but not allelic frequencies?

Is it possible for a population's genotype frequencies to change from one generation to the next but it's alleles stay constant? As long as there is no natural selection, inbreeding or mutation, the allele frequency will remain constant.
