Genetic equilibrium, as defined by obedience to the Hardy-Weinberg principle, is the basis of measuring all evolutionary change. Study populations (of real organisms) are compared to the ideal of genetic equilibrium, and if they do not measure up to the ideal in any way, this is a force that is bringing about evolutionary change.

Evolution is measured at the population level with genetic equilibrium as the standard.

According to the Hardy-Weinberg principle, both the ratios of genotypes and the frequency of alleles remain constant from one generation to the next in a sexually reproducing population, provided other conditions are stable.

It is a state within the population where the genotype and allle does not change.

------quote------

Genetic equilibrium is an ideal or theoretical state that provides a baseline to measure genetic change from.

Genetic equilibrium means a gene pool is not evolving.

-quote-

"A genetic equilibrium occurs when an allele within a gene pool is not changing in frequency (i.e. evolving). For this to be the case, evolutionary forces acting upon the allele must be equal and opposite. The only basic requirement is that the population be large enough that the effects of genetic drift are minimised."
