Inclusive fitness is a concept in evolutionary biology that includes not only an individual's own reproductive success but also their influence on the reproductive success of their relatives, considering the degree of relatedness.
Answer
Inclusive fitness is a theory that proposes an organism's genetic success is derived from cooperation and altruistic behavior, including helping relatives reproduce to pass on shared genes.
Inclusive fitness is a theory in evolutionary biology. It states that an organism's genetic success is derived from cooperation and altruistic behavior. It considers how an animal can increase their genetic success indirectly by helping relatives reproduce, thus enhancing the survival of shared genes.

More Information
Inclusive fitness was first defined by W.D. Hamilton in 1964. It is also known as kin selection theory.
Tips
A common mistake is to only consider the individual's direct reproductive success. Inclusive fitness also includes the reproductive success of relatives, weighted by their genetic relatedness to the individual.
