Which of the following statements are true regarding inclusive fitness? A. It is the sum of direct and indirect fitness effects of an individual’s behavior B. It provides evolutionary explanation for altruistic behavior C. It is judged by the number of offsprings

The inclusive fitness of an organism is judged by the number of offspring it has, how they support them, and how their offspring could support others. The concept serves to explain how natural selection can perpetuate altruism. If there is an 'altruism gene (or complex of genes) that influences an organism's behavior to be helpful and protective of relatives and their offspring, this behavior also increases the proportion of the altruism gene in the population, because relatives are likely to share genes with the altruist due to common descent.
