The anterior dorsocentral bristle is missing in 61% of wgSp-1
flies. When present, it is 14% shorter than normal.
females have reduced vaginal plates and tergite eight and the vulva is mainly absent. wgl-16
males lack the penis apparatus and most of the clasper, and the lateral plates are fused.
A rearrangement and increase in the number of large bristles on the sternopleurite. When in combination with wgspd-fg
homozygotes the level of wing etching is increased (compared to wgspd-fg
homozygotes). When in combination with other null or hypomorphic alleles the mutants are viable. Transheterozygotes lose one or both of the anterior dorsocentral macrochaetes. Transheterozygotes with wgSp-1
exhibit occasional etching of the wing margin and hold their wings in an abnormal out-stretched position.
Homozygous second leg imaginal dics exhibit a severe overgrowth on the dorsal side causing additional folds. wgP
individuals are lethal. Adult escapers from this cross lack one or both anterior dorsocentral bristles and more rarely also the posterior postalar bristle and the presutural bristle. They also exhibit loss of distal antennal segments and in rare cases exhibit antennal duplication. wgl-17
flies are viable and exhibit loss of anterior dorsocentrals and loss of microbristles located in the wg
-expression domain of the notum. wgl-17
flies in addition exhibit loss of distal antennal segments. Individual in combination with wgSp-revP
are pupal lethal and in combination with wg1
Extra bristles on the sternopleurite.
Sternopleural bristles increased in number. At 19oC, wild type; at 25oC, overlaps wild type; at 28oC-30oC, no overlap. Apparently does not affect sternopleural bristles on metathoracic segment converted by bx to a mesothoracic segment (Waddington, 1939). RK2. Homozygous lethal.
