The phenotypes of transgenic lines (P) were examined in males heterozygous (P/+) or homozygous (P/P) for the construct.
Number of tested transgenic lines. Figures in parentheses show the number of lines in which flies acquired a new y phenotype in comparison with flies from the starting line.
Number of flies with similar levels of bristle pigmentation. The degree of variegation in bristles of the thorax and head: 1, loss of pigmentation in all bristles at thorax and head; e-v, extreme variegation (only one to three bristles on thorax and head are pigmented); m-v, moderate variegation (about half of bristles are yellow); w-v, weak variegation (only one to three bristles on thorax and head are yellow); 5, pigmentation of all bristles as in wild-type flies.
