Small effective population size

Webb4. The population size does matter, but, unless the sample size is a large proportion of the population, it matters so little that it can be ignored. If N is the population size and n is the sample size, then the correction factor is. N − n N − 1. so, e.g. if you were doing polling for a national election, it would make essentially no ... WebbThe effective population size ( Ne) is defined as the size of an idealized Wright–Fisher population ( Fisher 1930; Wright 1931 ), which would give the same value of some specified genetic property as in the population in question ( Crow & Kimura 1970 ).
