Studies on the sex-specific lethals of Drosophila melanogaster. VII. Sex-specific lethals that do not affect dosage compensation.

Abstract
Autosomal, non-maternal effect, sex-specific lethals of D. melanogaster were examined by lactic-aceto-orcein staining and 3H-uridine incorporation autoradiography of larval salivary gland chromosomes. Two classes of lethals were revealed. One class, which affects dosage compensation, in addition to the male-specific lethals, mle, Msl-1 and msl-2 previously reported by Belote and Lucchesi, now includes a male-specific lethal, mle(3)132. The other group which shows normal dosage compensation is a new group and includes a male-specific lethal, C52, and a female-specific lethal, fle(3)100. A possible of the lethals in the latter group is discussed.
