Insertion within the first exon of the vib gene.
vibS045002c mutants have non-motile sperm.
Individual spermatids from vibS045002c/Df(3R)Dl-BX12 males have multiple nuclei associated with an enlarged nebenkern in 30% of spermatids. Mutants show cytokinesis failure during male meiosis.
vibS045002c/vibS110416 mutants show cytokinesis failure during male meiosis.
Separable from: P{lacW}S045002a. Separable from: l(3)S045002bS045002b.
Based on the lethal stage of hemizygous alleles (over Df(3R)Dl-BX12), the following vib alleles can be ranked from strongest to weakest as follows: vibj7A3 > vibS110416 > vibEP513 = vibj5A6 > vibS045002c > vibEP651.
