Parent-offspring correlations under full-sib and parent-offspring mating systems

Abstract

A study of the parent-offspring correlations under full-sib mating and parent-offspring mating system has been conducted. A general theory for obtaining the correlation between one parent and k offspring, as well as the correlation between both the parent and k offspring under a given system of mating has been developed, both for the autosomal as well as sex-linked genes. Using this theory and the generation matrices for different mating types under full-sib or parent-offspring mating system with autosomal or sex-linked genes, parent-offspring correlations have been worked out. A comparative study of these correlations, graphically as well as numerically, has been carried out.
