The inbreeding effective size can be found by solving This is although researchers rarely use this equation directly. Theoretical example: overlapping generations and age-structured populations [ edit] When organisms live longer than one breeding season, effective population sizes have to take into account the … See more The effective population size (Ne) is a number that, in some simplified scenarios, corresponds to the number of breeding individuals in the population. More generally, Ne is the number of individuals that an See more Alternatively, the effective population size may be defined by noting how the average inbreeding coefficient changes from one generation to the next, and then defining Ne as the size of the idealized population that has the same change in average inbreeding … See more In an idealised Wright-Fisher model, the fate of an allele, beginning at an intermediate frequency, is largely determined by selection if the selection coefficient s ≫ 1/N, and largely determined by neutral genetic drift if s ≪ 1/N.
