Hardy-Weinberg Equation
The Hardy-Weinberg Equation, a fundamental concept in population genetics, provides a mathematical framework for understanding genetic equilibrium within a population. Developed independently by G. H. Hardy and Wilhelm Weinberg in the early 20th century, this equation describes the relationship between allele frequencies and genotype frequencies in an idealized, non-evolving population. By analyzing factors such as mutation, migration, genetic drift, and natural selection, the equation serves as a cornerstone in assessing evolutionary processes and genetic variation within populations. Its elegant simplicity offers invaluable insights into the dynamics of genetic inheritance and population genetics.
