On the composition of timed systems, he studied were C-Sh-Wx (C affects aleurone colour in the presence of certain other genes; Sh affects the degree of shrinkage of the endosperm at maturity; Wx affects the chemical composition of the endosperm). The c.o.v.’s as extensively studied by . (1919) and . (1922) were 3.5 for the region C-S
