Gene mutation causes the phenotype frequency in a population to change after each generation.
The frequency of the populations alleles. Their gene frequency must change to have evolution.
competition between organisms
Allele frequency is stable The phenotype frequency does not change.
In Hardy-Weinberg equilibrium, allele frequencies in a population remain constant from generation to generation. This means that the population is not evolving. Factors such as no mutation, no gene flow, random mating, large population size, and no natural selection contribute to Hardy-Weinberg equilibrium.

The phenotype frequency does not change
Natural selection causes changes in the frequency of certain genetic traits within a population over time. Traits that confer a survival or reproductive advantage are more likely to be passed on to the next generation, leading to an increase in those beneficial genetic traits in the population.
National selection can change the frequency of traits in a population by favoring certain traits that provide a survival or reproductive advantage. Over time, individuals with these advantageous traits are more likely to survive and pass their genes on to the next generation, leading to an increase in the frequency of those traits in the population. Conversely, traits that are not advantageous may decrease in frequency or be selected against.
organisms compete for shelter
Generation-to-generation change in allele frequencies in a population is known as evolution. This change can be the result of various factors such as natural selection, genetic drift, gene flow, and mutation. Over time, these processes can lead to the emergence of new traits and variations within the population.
A population in which the allele frequencies do not change from one generation to the next is said to be in equilibrium.
The term used to describe the generation-to-generation change in allele frequencies of a population is simply evolution. Simple answer for a complicated-looking question. ;) Hope this helps.
