  • (Left) Ability of lines to repress P-induced gonadal dysgenesis: replicate sets of 3–10 females of the tested lines were crossed with 5 Harwich-2 males (A* assay). Progeny were allowed to develop at 29°. For each replicate test cross, 50 to 100 ovaries were examined in the progeny. m, s, and n are, respectively, the mean percentage of GD sterility, the standard deviation among replicates, and the number of replicates performed. (Right) Combination effect between the tested lines and a P-lacZ telomeric insertion. The P-1152 line carries a P-lacZ insertion at 1A. P-1152 females were crossed with males of the tested lines at 20°. Replicate sets of 3–5 G1 females [Cy+], carrying both the P-1152 transgene and the tested cluster, were crossed with 5 Harwich-2 males (A* assay) at 29° and the percentage of GD sterility was measured.
