RK1. Malpighian tubule colour: contain brown pigment; like red1.

Eye colour: brown with whitish highlight. Paler than se1, less purplish than pn1. The eye colour phenotype is autonomous in mosaics (derived from ncd1). Malpighian tubule colour: bright yellow, like wild-type. Testis colour: bright yellow, like wild-type. Eye colour: cho1/cho2 eye colour is indistinguishable from either cho1 or cho2.
