Influence of Sex on Selection III. Joint Contributions of Sex-Linked and Autosomal Genes

Abstract

The joint contributions of sex-linked and autosomal genes to mass and general combining ability selection procedures are examined. Detailed results are given for n consecutive cycles of selection, and for relaxation from selection, with regard to a two·locus model which involves both sex-linked and autosomal loci. This model permits (1) an arbitrary number of alleles at each locus; (2) an arbitrary system of dominance parameters; (3) an arbitrary system of sex-linked-autosomal epistatic parameters; and (4) different genotypic values for the same autosomal genotype in the two sexes. This last condition implies that the model incorporates "sex-influenced" as well as "sex-linked" inheritance.
