  • Genetic interaction between the butyrate-sensitive PEV suppressorSu(var)2-1 and E(z)Trm was tested in the absence of the wild-type E(z) gene product by crossing Su(var)2-13/SM6; E(z)Trm/TM3 females to E(z)60/TM6 males, and the homeotic phenotype of the viable E(z)Trm/E(z)60 offspring was examined in the presence and absence of the mutant Su(var)2-13 allele.
