Abstract

Studies on the mating systems of Sciara ocellaris maintained in a population cage for one year (13-14 generations) revealed that flies mate assortatively for 9 out of 15 single polytene chromosome-band variants commonly found in this species. The null hypothesis of random mating could not be rejected for five of the remaining six bands, and for one band none of the systems of mating examined fit the data. The significance of these facts for the maintenance of the cytological visible gene variability in Sciara ocellaris is discussed.
