Title The minimal interspecific introgression resulting in male sterility in Drosophila.
Journal Genet Res
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.
