D. mauritiana P[w+]-marked chromosome segments were introgressed into a D. sechellia w background via 15 generations of backcrossing (A). The P[w+] insertion carries a mini-white gene that acts as a partially dominant visible eye-color marker for selecting heterozygous females for each backcross. Introgressions were made homozygous on the autosomes (B) and the X chromosome (C), and tested for postzygotic hybrid incompatibilities.

Figure 2. Distribution of D. mauritiana Introgressions in the D. sechellia Genome. From: High-Resolution Genome-Wide Dissection of the Two Rules of Speciation in Drosophila.

Inverted triangles above each chromosome show P[w+] insertion sites: black indicates hybrid inviable; red indicates hybrid male-sterile; white indicates hybrid fertile or untested. Horizontal lines below each chromosome show the approximate sizes of 108 of 142 introgressions. Arrows indicate that D. mauritiana material extends beyond the marker resolution at that location. Black indicates hybrid inviable introgressions; red indicates hybrid male-sterile introgressions; gray indicates hybrid fertile introgressions. The breakpoints of an inversion difference on chromosome arm 3R between D. melanogaster and the D. simulans clade species (D. simulans, D. mauritiana, and D. sechellia) are shown as brackets.
