B chromosomes significantly modify position-effect variegation. For each line, females carrying the reporter gene were crossed to males of the genotypes listed. (A) In(1)wm4 flies were examined for their degree of PEV from crosses with a wild-type control, WT+B, or mtrm126/TM3. (B) Four insertion reporter lines with the w+ gene inserted in the pericentric region of chromosomes 2 (39C-3 and Hs-5), 4 (118E-10), and the X (118E-32), were examined when crossed to a wild-type control or WT+B.
