Does not show significant repression of P-induced dysgenic sterility when P{lacW}50C.x7 females are crossed to P males. Does show significant repression of P-induced dysgenic sterility when females carrying both P{lArB}A171.1F1 and P{lacW}50C.x7 are crossed to P males.

(Ronsseray et al., 2001)

Derivative of P{lacW}50C.x3 or P{lacW}50C.x4 with more extreme variegation in eye color; 7 tandem copies of the P{lacW} element at 50C; responds to modifiers of PEV.
