rRNA gene copy number, about 100.
lethal | female (with In(1)bbDf)
viable
visible | recessive
macrochaeta
Females homozygous for bbds or heterozygous for bbds and a mutant allele of bb are bb in phenotype. bbds/In(1)bbDf females are lethal.
RK2.
Goldschmidt.
The allele present in some stocks marked bb.
bbds-like alleles have been reported by Stern and Ogura (FBrf0002272) and by Lindsley, Edington, and Von Halle (FBrf0013319). Presumably, this difference between bb and bbds is a property of the bb locus and bb is not equal to bbds.
No longer deficiency sensitive.
