Multiple copies of dCBP do not enhance or suppress PEV. Neither the dCBPTr42 nor the dCBPTr31 chromosome enhance or suppress PEV, and there is no significant difference between the distribution of variegation seen in the y wm4 flies and the y wm4; dCBPTr42/+ flies (0.2 < P < 0.3) and the y wm4; dCBPTr31/+ flies (0.3 < P < 0.5). Although the flies carrying 4 copies of dCBP appear to suppress PEV, the distribution of variegation in these flies is not different from that seen in the y wm4 flies (0.05 < P < 0.02). An experiment in y wm4/y w flies had similar results (not shown).
