Lethality occurs during third instar larval or pupal stages. Mutants exhibit visible disc abnormalities. In tergites, clones with normal size and frequency are recovered. Clones cannot be recovered in the wing disc.
Homozygous larvae have imaginal discs similar in size and shape to those of kuzk01405 homozygous larvae. Homozygous clones induced in the thorax at 48-72 hours after egg laying produce tufts of microchaetae and areas of naked cuticle.
