Figure 1.—
Organization of the six chromosomal elements in haploid female genomes of representative Drosophila species. Each chromosomal arm is labeled with its Muller element designation based on Table 9-4 from Powell (1997) with exceptions/additions for D. ananassae (Tobari 1993), D. willistoni (Papaceit and Juan 1998), and D. mojavensis (Wasserman 1982). The consensus relationships among species are represented by the cladogram disregarding absolute times of divergence.
