The P{XP}orb2d01793 insertion maps within both orb2 and CG43783 (the genes share some exons at the 5' end, including some coding sequence).
Fertility of homozygous males is substantially impaired. Fertile orb2d01793/Df(3L)ED4416 males are occasionally recovered.
orb2d01793 mutants do not exhibit any obvious defects in locomotion and activity. Flies were able to return to a standing position following vortexing at a similar rate to wild type flies and show normal climbing ability.
The rough eye phenotype observed in Fmr1sev.PW flies is suppressed in a orb2d01793/+ background.
orb2d01793/orb2[+] is a suppressor of eye phenotype of Fmr1sev.PW
