Detailed Description

Statement

Reference

Heterozygotes do not show a malformed leg phenotype. Heterozygotes have normal bristle morphology. Sb^Ebr20/Df(3R)sbd105 adults have a stubble bristle phenotype. Homozygotes show 10 +/- 3% embryonic lethality and 100% of homozygous larvae fail to form pupae. Homozygotes show larval moulting defects.
