For each cross, flies were mated in fresh vials and transferred to new vials for the number of days indicated. While no females from the first cross were fertile, the other six crosses were sufficiently fertile to establish balanced stocks. Among the progeny from the last cross, we cannot distinguish a maternally-inherited X chromosome (yd2 w1118 P{ry+t7.2 = ey-FLP.N}2) from a paternally-inherited X chromosome (y w), so both are indicated only as y w. Q1 is the third chromosome transposon insertion, P{w+mC:PRE[Scr7-8]}Q1. Dp(1;4) is Dp(1;4)193, y+ svspa-pol.
