What does it mean if the allele frequency in a population consistently changes?

Answer 1

When allele frequency in a population consistently changes it means the population is evolving.

Microevoluion, which refers to evolution on a small scale, is defined as a change in the frequency of alleles in a gene pool over time.

This might be the result of mutation or the introduction of new alleles through gene flow.

Natural selection causes the frequency of favourable alleles to gradually increase within a population, which could also be the cause.

In a small, recently formed population, allele frequency may also fluctuate as a result of an initial sampling error when some alleles were accidentally lost forever, or as a result of genetic drift.

If the allele frequency in a population consistently changes, it indicates genetic evolution or a shift in the prevalence of specific genetic variations over successive generations.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
