wing vein L5 | adult stage (with sbb6)
sbbplt/Df(2R)BSC334, sbbplt/Df(2R)ED3683, sbbplt/sbbBG01610, sbbplt/sbb6, and sbbplt/sbbk00702 mutants exhibit a wing vein phenotype wherein wing vein L5 fails to reach the wing margin, and males of these mutants also fail to copulate; but sbbplt/Df(2R)BSC483, sbbplt/Df(2R)Exel7153, sbbplt/Df(2R)BSC335, sbbplt/Df(2R)BSC399 and sbbplt/+ mutants do not show these phenotypes.
sbbplt/sbbBG01610 and sbbplt/Df(2R)BSC334 mutant males exhibit significantly decreased courtship indices, and reduced incidence of licking and attempted copulation as compared to sbbplt/+ controls. sbbplt/Df(2R)BSC334, but not sbbplt/sbbBG01610 males exhibit significantly decreased wing extension during courtship, as compared to sbbplt/+ controls.
sbbplt/+, sbbplt/sbbBG01610 and sbbplt/Df(2R)BSC334 mutant males do not show any obvious structural anomalies in their external genitalia and associated muscles.
