The Hardy-Weinberg principle shows that if the population is large , inheritance alone does not cause changes in allele frequency.

Hardy-Weinberg Principle

The concept that in the absence of evolutionary forces, the proportions of both alleles and genotypes within a population will not vary from one generation to the next.

Allele Frequency

The relative frequency of an allele (variant of a gene) at a particular gene locus in a population, important in the study of genetic variation.

Inheritance

The process by which genetic information is passed on from parents to their offspring.
