233 Effective population size
Effective population size is the number of mature individuals of a species or population that contribute to the production of viable offspring and the maintenance of genetic variation.
Note.
Effective population size is usually much less than total population size due to the presence of juveniles, old (senescent), diseased, moribund and other non-breeding individuals, uneven sex ratios, unsuitable environmental conditions for breeding and recruitment at some localities and in some years, variation between family sizes and fluctuating population sizes between generations.
