Abstract

Some genetic effects of thinner, benzene and toluene were studied in Drosophila melanogaster, namely sex-chromosome loss and non-disjunction in males and females. The order 'of toxicity was benzene > toluene > thinner. Viability was reduced by benzene and toluene but not by thinner. Sex chromosome loss and non-disjunction were induced in males only at the highest concentrations of benzene and toluene. Thinner did show genetic effects.
