The Hardy-Weinberg Law Assumes an Idealized Population in Which Mating

Essay

The Hardy-Weinberg law assumes an idealized population in which mating is random and allele frequencies are constant. Allele frequencies can change in human populations over time but because the changes are often slow and occur in small increments, they often have minor effects. However, certain types of non-random mating can have a major effect on the accuracy of the Hardy-Weinberg predictions. What types of non-random mating occur that can threaten the applicability of the Hardy-Weinberg Law?
