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.
Bsb1, Priunspecified has visible | dominant phenotype
Bsb1, Priunspecified has macrochaeta phenotype
Heterozygotes with Bsb1 exhibit bristles reduced to very short stubs.
