    Myth: Allele frequency is only relevant for medical genetics.

    Common Misconceptions

    Alleles are different forms of a gene, and their frequency in a population is determined by the laws of Mendelian genetics. The Hardy-Weinberg principle states that allele frequencies remain constant in a population over generations if the population is isolated, has no mutation or gene flow, and is large enough. However, in real-world populations, various factors such as genetic drift, mutation, and selection can influence allele frequencies.
