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.
Rhabdomeres R1-6 show complete degeneration 7 days after eclosion, but rhabdomeres R7 and R8 show no degeneration.
