Selection in Reference to Biological Groups I. Individual and Group Selection Applied to Populations of Unordered Groups

Abstract

A selection theory designed to accommodate interactions among genotypes is presented. This involves defining unordered groups of genotypes among which interactions may occur, and describing populations of groups generated as combinatorial products of base populations. Gene models are developed which consist not only of direct contributions of the genotypes they represent but also of associate effects from other genotypes in the group.
