Selection Differentials

Selection differentials and selection coefficients.

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 and mortality differentials.

The Office of Population Censuses and Surveys Longitudinal Study provides reliable mortality data by a much wider range of characteristics than are available for other national sources. Although it is based on only a 1% sample of the population, it broadens the scope of mortality analysis and permits study of changes in relationships using different aspects of the time dimension.
