Allele frequency describes how often an allele (a variant of a gene) appears in a population. In this video, eye color is used as an example, with brown (B) eyes being dominant and blue (b) eyes …

Microevolution, or evolution on a small scale, is defined as a change in the frequency of gene variants, alleles, in a population over generations. The field of biology that studies allele …

The Hardy-Weinberg equation can help to estimate allele frequencies in a population. Dominant (p) and recessive (q) allele frequencies and genotype frequencies can be calculated using the …

In this article, we’ll examine genetic drift, an evolutionary mechanism that produces random (rather than selection-driven) changes in allele frequencies in a population over time.

Genetic drift involves changes in allele frequency due to chance events – literally, "sampling error" in selecting alleles for the next generation. Drift can occur in any population of non-infinite size, …

The Hardy-Weinberg equilibrium is a principle that helps to predict allele frequencies in a population. It assumes no selection, no mutation, no geneflow, random mating, and large …

Genes and alleles are key players in heredity. Genes are sections of DNA that code for specific proteins or functional RNA. Alleles, on the other hand, are different versions of the same gene. …

Oops. Something went wrong. Please try again. Uh oh, it looks like we ran into an error. You need to refresh. If this problem persists, tell us.

The Hardy-Weinberg equation assumes stable allele frequencies in a population. Key conditions include no mutation, random mating, no gene flow, infinite population size, and no selection. …
