For a population containing 70 females and 30 males, what is the effective population size, ne

The effective population size will be 100. As the population size is the total number of individuals in the population. Quadrant and mark recapture are the two important methods to determine the population size. Scientists estimate size of the population by taking samples from the population and using this to make inferences about the population.

Equation is (4 x Nm x Nf) / (Nm + Nf) where

Nf is number of females

Nm is number of males

= (4 x 30 x 70) / (70+30)
