Abstract
Somatic clones doubly homozygous for Antpw10 and Rg-bx mutations were induced with X-ray and examined for the cuticular morphology of these clones covering the antenna. The Antp- Rg-bx- clones on the antenna show nearly normal arista together with bristles of the leg type on the basal cylinder and the third antennal segment whereas the Rg-bx- clones transform the distal antennal tissue to the tarsal segments of the leg. The absence of the Rg-bx+ function is suggested to cause the hypermorphic expression of the Antp locus in the antennal tissue.
