FlyBase curator comment: this entry is used to capture phenotypic information when the particular allele (or allele combination) used by the author could not be determined but the context of the experiment suggests that the phenotype being described is some kind of loss of function.
Darkunspecified/Ark[+] is a non-suppressor of visible phenotype of hidGMR.PG
Darkunspecified/Ark[+] is a non-suppressor of visible phenotype of rprGMR.PW
Darkunspecified/Ark[+] is a non-suppressor of eye phenotype of hidGMR.PG
Darkunspecified/Ark[+] is a non-suppressor of eye phenotype of rprGMR.PW
Arkunspecified/+ has little effect on the reduced eye phenotype caused by expression of rprGMR.PW or WGMR.PG.
