Inclusive fitness in animals
Did you know?
WebInclusive fitness is described as a combination of one's own reproductive success and the reproductive success of others that share similar genes. [1] Animals may increase their inclusive fitness through kin selection. WebInclusive fitness suggests that altruism occurring among organisms who share a given percentage of genes enables those genes to be passed on to subsequent generations. Inclusive fitness applying only to relatives is called kin selection. Hamilton’s rule ( r × B > ℂ) specifies the conditions under which reproductive altruism evolves.
In The Selfish Gene, Dawkins reported that some question the idea that parental investment (parental care) contributes to inclusive fitness. The distinctions between the kind of beneficiaries nurtured (collateral versus descendant relatives) and the kind of fitnesses used (inclusive versus personal) in the parsing of nature are independent concepts. This orthogonality can best be understood in a thought experiment: Consider a model of a population of animals such as croco… WebFor example, a female lion with a well-nourished cub gains inclusive fitness by nursing a starving cub of a full sister because the benefit to her sister ( B = one offspring that would otherwise die) more than compensates for the loss to herself ( C = approximately one quarter of an offspring), since the survival probability of her own, …
