R if also depends on all the demographic details and the current state of the population.

It is assumed that personal fitness can be written as the sum of components caused by. The derivations were demonstrated to be unrelated by corresponding parts of the two identical formulae for r displaystyle r being derived from the genotypes of different individuals. Inclusive fitness theory is an approach that is based on assigning fitness effects of social interactions to individuals. Thus in line with the very general conditions for inclusive fitness there is a great deal of complexity here reflecting the complexity in the original model.
