title: Cytological mapping of Om mutants of Drosophila ananassae.
abstract: Semidominant, optic morphology (Om) mutants in Drosophila ananassae have been genetically mapped to at least 25 loci throughout the genome (Hinton, 1984; 1988). Among them, four X-linked Om mutants were proved to be associated with the insertion of a transposable element, tom (Shrimpton et al., 1986; Tanda et al., 1988). In the present study, cytological mapping of autosomal Om mutants was carried out by in situ hybridization to polytene chromosomes using a cloned tom element as a probe. The cytological site for each autosomal Om mutant has been determined to a single band of the salivary gland chromosomes.
