Question

The fact that genes associated with altruism are favored by natural selection if they lead to the reproductive success of an altruist's closest relatives is called _____.  
A) inclusive fitness
B) survival of the fittest
C) evolution
D) inbreeding
E) selective mating

Quizplus · Accepted Answer

The fact described in the question is an example of inclusive fitness, which refers to how genes spread through a population by increasing the reproductive success of not only an individual, but also their genetically related kin. In contrast, survival of the fittest refers to how the most adapted individuals survive and reproduce in a given environment, and evolution is the process by which species change over time. Inbreeding and selective mating are also processes that affect the genetic makeup of a population, but they are not directly related to the concept described in the question.
