rij, instantaneous rate of increase (per day) of a population, all of whose members have the l(x) and m(x) schedules of karyotype AiAj; Rij, mean lifetime fecundity (as female eggs) of an AiAj female at birth; Wij, relative Darwinian fitness of karyotype AiAj; r, instantaneous rate of increase (per day) of an equilibrium population.
