*
In crosses, all F1 females were either 100% WT (yellowish body coloration and red eyes) or 100% albino (Alb) (white bodies and no eye color). Sample sizes for F1s for all crosses were ≥85.
†
Although progeny from complementation crosses with W-Alb-2 were albino (white bodies lacking bright red eyes), faint eye color was apparent in F1 adult females, mirroring the phenotype observed in adults of the W-Alb-2 strain.
‡
Denotes that each of W-Alb-7, W-Alb-8, W-Alb-10, W-Alb-11, and W-Alb-14 were crossed to males of Alb-JP (in all cases, progeny were albino in phenotype).
