Selection in Reference to Biological Groups III. Generalized Results of Individual and Group Selection in Terms of Parent-Offspring Covariances

Abstract

Transference of the model-building unit from that of the gene to that of the entire genotype permits the consequences of individual and group selection to be given in terms of parent-offspring covariances. This, in turn, solves two basic problems: (1) extending the genetic analysis to any arbitrary level of complexity; and (2) formulating the prediction equations of genetic advance in terms of parameters which are directly estimable
