население

население

A more or less distinct group of individuals within a species who are reproductively isolated from other groups. In other words, they restrict their mate selection to members of their own population. This is usually due to geographic and/or social barriers to mating with outsiders. Members of a completely isolated small population tend to have similar genetic characteristics due to generations of inbreeding.
