Detailed Description
Statement
Reference

Mutants show a significant developmental delay and somewhat smaller larval body sizes than normal, but no obvious morphological neuromuscular junction phenotypes.

Enhances the Cbx phenotype in Ubx1:Cbx-1/In heterozygotes.

Developmental delay and reduced bristle phenotype.

Heterozygotes have shorter bristles than wild type flies. Eclosion is delayed by 24 hours.

Bristles very small; aristae often reduced; venation px-like. Hatches late. Viability about 70% wild type and variable. Fertility good. RK2.
