      Comments

      Eye color complementation group: III malF1 does not complement mal1 when kept at 29oC-30oC throughout development; complementation occurs provided development proceeds at 25oC during either of the two critical periods: the third quarter of the third larval instar or the middle of the pupal stage (Schalet, 1971).
