      Reference

      Homozygous larvae are 40% the length and the same width as their heterozygous siblings, length differences arise during larva formation as embryos are about the same length as their heterozygous siblings. The larval cuticle of homozygotes is weak, as seen by frequent holes at random positions in the exoskeleton. The dorsal and ventral larval cuticle is composed of pattern elements found in the ventrolateral position in the wild-type larval cuticle.
