Summary

1. A cytogenetic analysis of 18 independent lz mutants is presented.

2. On a phenotypic basis the mutants can be separated into three classes.

3. The results of a recombination analysis show that each of the 18 mutants can be assigned to one of three loci. No case where a lz mutant involved more than one locus was found.

4. Both phenotypic and recombination evidence place the amx mutant outside the lz pseudoallelic system.

5. Cytologically the lz pseudoalleles have been localized to section 8D of the salivary X chromosome.

6. The relevance of the data presented to the nature of pseudoallelism is discussed.
