| Abstract |
Introgression of Drosophila simulans genes into the Drosophila melanogaster genome provides an ideal system for analysing genetic incompatibility between species. Females and males homozygous for the introgression Int(2L)S (cytologically, 30F3-31C5 to 36A2-7) are sterile. Genetic dissection of the proximal part of the introgression (34D1-3 to 36A2-7) has indicated that introgressions of 0.7-1.6 Mb size result in male sterility when homozygous. In the present analysis we examine the distal part of the introgression (30F3-31C to 34D1-3) and reveal that introgressions with similar DNA content (1.8-2.1 Mb) result in male sterility. Compared with introgressions between the more closely related species Drosophila mauritiana and D. simulans, the minimal introgression resulting in male sterility is smaller by several-fold.
