A Gene Complex Controlling Segmentation in , a repressor of the complex. The wild-type and mutant segmentation patterns are consistent with an antero-posterior gradient in repressor concentration along the embryo and a proximo-distal gradient along the chromosome in the affinities for repressor of each gene’s .-regulatory element.

In the Name of Cultural Studies,ere mated ., all of the F. had abnormal eyes, but these varied in size from that of S/+ (see Table IV) to a narrow slit of red pigment on which only a few facets were scattered. A clue to the manner of inheritance of the type with narrow eyes was found by mating a narrow-eye male to a wild-type female, with the result shown in Table I:

Later, Wright2 suggested that Bar itself had something additional present which when lost by unequal crossing-over would give back a normal chromosome (Bar-reverted).
