Hardy-Weinberg equilibrium provides a mathematical model that describes how allele frequencies in a population remain constant from one generation to the next, under certain ideal conditions. One of the key insights from this model is that dominant alleles do not automatically replace recessive alleles in a population, which is why recessive alleles can persist over time even if they are not expressed in the phenotype as frequently as dominant alleles. This principle helps explain genetic diversity and why certain genetic traits do not disappear over time.
