If the frequency of alleles in a population remains constant, the population is at Hardy-Weinberg equilibrium. There are five conditions for Hardy-Weinberg equilibrium. It is very important for you to know these conditions, so enter them neatly into the box below. CONDITIONS FOR HARDY-WEINBERG EQUILIBRIUM. Condition.

Effective population number (or more commonly, effective population size, N e) is the evolutionary analogue to the census size, N. N e, rather than N, determines the rate of random genetic drift and hence the rates of allele frequency change, loss of genetic variability, and increase in inbreeding.
