Figure 1. Sex chromosomes in higher Diptera revealed by genome analysis.

Figure 1

Evolutionary relationship inferred from 185 conserved protein-coding genes (93134 amino-acids) using PhyML, and male/female coverage ratio across chromosome elements (Muller elements A–F) in the Diptera species studied. X chromosomes (in red) have only half the read coverage in males vs. females. Boxes extend from the first to the third quartile and whiskers to the most extreme data point within 1.5 times the interquantile range.
