Specifically, it has typically been implicitly assumed that mating is at random, family size follows a Poisson distribution, . is constant, and the sex ratio is 1:1. Perhaps more significantly, it has gener

If selection is not acting continuously in one direction, is there a most fit genotype? If so, why is it that selection does not act to eliminate a

I have approached the problem not from the point of view of an animal or plant breeder but from that of one interested in understanding the evolution of quantitative traits in wild populations. The subject is large with a considerable body of theory: I generally present the ass978-0-412-12971-1978-1-4615-4080-9
