effective population size
effective population size The average number of individuals in a population that actually contribute genes to succeeding generations. This number is generally rather lower than the observed, censused, population size, being reduced by the following factors:
a. a higher proportion of one sex may mate;
b. some individuals will pass on more genes by having more offspring in a lifetime than others;
c. any severe past reduction in population size may result in the random loss of particular genotypes.
