WebIn the breeder's equation, R = h 2 S. In animal and plant breeding, S is determined by the breeder. In natural selection, S is determined in part by the intensity of the struggle for existence in step 3 above, and by the adaptive landscape. The breeder's equation can be rewritten as . R = V A β ,
