the accumulation of mutations in small populations can be divided into three phases. in the second phase a population starts in mutation/selection equilibrium, mutations are fixed at a constant rate through time, and the population size is constant because the fecundity exceeds mortality. however, after a sufficient number of mutations have been fixed in the population, the birth rate is slightly less than the death rate, and the population size begins to decrease. the smaller population size allows for a more rapid fixation of deleterious mutations, and a more rapid decline of population size, etc.

the effective population size is the number of individuals that an idealised population would need to have in order for some specified quantity of interest to be the same in the idealised population as in the real population. idealised populations are based on unrealistic but convenient simplifications such as random mating, simultaneous birth of each new generation, constant population size, and equal numbers of children per parent. in some simple scenarios, the effective population size is the number of breeding individuals in the population. however, for most quantities of interest and most real populations, the census population size "n" of a real population is usually larger than the effective population size "n". the same population may have multiple effective population sizes, for different properties of interest, including for different genetic loci.
