A position effect variegation (PEV) phenotype can be used to identify new genes that regulate heterochromatin formation. For example, strains of Drosophila melanogaster with the white variegation phenotype can be subjected to mutagenesis to screen for mutations in other genes that suppress PEV, meaning the mutation results in a lower white pigment production. Using what you know about the enzymes that control heterochromatin spreading, describe one mutation that you would expect to be a suppressor of variegation
