The Hardy-Weinberg principle relates to:
- Frequency of alleles in a population: This principle describes how allele frequencies in a population will remain constant from generation to generation in the absence of evolutionary influences such as mutation, natural selection, gene flow, or genetic drift. It provides a mathematical model to predict the genotype frequencies in a population when certain conditions are met.
Understanding the Hardy-Weinberg principle is essential in population genetics as it helps scientists study genetic variation within populations and determine if evolutionary forces are at play based on observed allele frequencies.
