Selection differentials and selection coefficients
Genetics.
1978 Feb.
Abstract
Proof is offered that s approximately ig for all forms of selection where fitness is a nondecreasing function of a normally distributed phenotype (called fitness potential); s is selection coefficient, i is standard selection differential, and g is standard differential effect of a locus genotype.Evidence is presented that the cost of selection does not limit genic polymorphism; that truncation selection is not necessary for high cost-efficiency; and that opposing directions of selection in a heterogeneous environment do not reduce cost-efficiency critically.
