WebMar 23, 2015 · When this sum, called the inclusive fitness effect, is positive, the trait should be favored by selection. For giving up one’s reproduction (fitness cost c) to benefit other individuals (total fitness gain b) related by r, the inclusive fitness condition is − c + rb > 0. Webequation in terms of relatedness coefficients. Price’s formula is then seen to be equivalent to the inclusive fitness deviation of a mutant individual. In Section 5 I discuss how relatedness is calculated, and in Section 6 I present the sex allocation example. 2. THE COVARIANCE FORMULA
