Summary Introduction

To determine: The effective population size (N_e) in a population of 100 prairie chickens, in which only 30 females and 10 males bred.

Introduction:

Effective population size (N_e) represents the number of individuals in a population that contribute offspring to the next generation. Effective population size can be mathematically calculated as follows:

$N_e=\frac{4N_f{N}_m}{N_f+N_m}$

Here,

$N_e$= Effective population size.

$N_f$= Number of effective females.

$N_m$= Number of effective males.
