F1 males from the cross of DGRP males to females of Bloomington stock 1712 (In(1)wm4 X chromosome; Df(2L)2802/CyO), so the F1 males carry the tester's white-mottled-4 X chromosome and one haploid genome of the DGRP line, Df(2L)2802 (non-curly) siblings, carrying a ~200 kb deletion in 25F2-25F5 that enhances variegation: position effect variegation (PEV) of the white-mottled-4 eye-colour reporter, measured as the first principal component (PC1) of the gray-card-normalized mean red, green and blue values of one imaged eye per 4-8 day-old male (higher values = more pigmented eyes, i.e. less variegation; unitless); mean per DGRP line, as in File S1 and used for the authors' GWAS [No unit]
