RESUMO
Five third-instar larval cuticle protein genes are placed on the left arm of the third chromosome. For these five genes, 12 variants and two induced mutants are described. All the naturally occurring variants are codominant. One EMS-induced mutant is characterized by the codominant appearance of a new protein, and a second by a recessive mutation that codes for a modifier of third-instar larval cuticle protein 5 (L3CP-5). All but the putative modifier gene map to within less than 0.3 map units of each other on the left arm of the third chromosome at approximately 11. We propose that these genes constitute a cluster of third-instar cuticle protein genes. The induced recessive mutant maps outside of the cluster to a region also on the left arm of the third chromosome. The proteins and their genes should prove useful for both developmental and evolutionary studies.
