Summary Introduction
To review:
The conditions in which the nonrandom mating can and cannot lead to the evolution.
Introduction:
The nonrandom mating can be present when the probability of the mating of two individual in a population is not same as for all another possible pair in the population. In this, the mating of the closely related individuals can be promoted or the mating of the distantly related individuals can be promoted.
