Idealised population

In population genetics an idealised population is one that can be described using a number of simplifying assumptions. One example is a Fisher-Wright population after R.A. Fisher and Sewall Wright, is a population whose members can mate and reproduce with any other member of the other gender, has a sex ratio of 1 and no overlapping generations. Another example is a Moran model, which has overlapping generations.

Deviation from the idealised population results in the effective population size being different from the census population size.
