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.
btszunspecified homozygous adults have reduced body pigmentation, shorter, thinner bristles, slightly rough eyes, occasionally crumpled wings and lay fewer eggs than wild-type. However, these flies are properly proportioned and show no obvious defects in coordination, feeding, or mating behavior.
