THE THEORY AND ANALYSIS OF DIALLEL CROSSES. II

Abstract

The diallel analysis of HAYMAN (1954b) is extended to include F, families. This greatly increases the accuracy of measurement of the components of genetic variation and of description of the gene distributions in the parents. The original diallel analysis was restricted to a certain simple genetic situation. The addition of F, data makes it possible, with the aid of HAYMAN’S (1957) test for epistasis, to distinguish some of the more complicated genetic systems that may arise but it is still not possible to estimate the magnitude of the departure of any of these other systems from the simple one. Experimental designs to suit the diallel analysis are given
