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.
fz2unspecified, fzunspecified has wing disc | somatic clone phenotype
fzunspecified fz2unspecified double mutant clones induced in the wing disc during the late second or third instar contain significantly fewer cells than their wild-type sister clones. Fragments of DNA, indicative of cell death, are repeatedly seen in cells of the small clones. Clone size is substantially increased in fzunspecified fz2unspecified double mutant clones if they are also expressing BacA\p35Scer\UAS.cHa under the control of Scer\GAL4αTub84B.PL.
