aThe ancestral state, when using D. virilis gene sequences as the outgroup, could not be determined for all apparently fixed mutations between the two chromosomal backgrounds.
bAccording to Vieira et al. (2001).
cFor the X/4 fusion Xc-inverted chromosomal background this may be an overcorrection, because it is not possible to infer the ancestral state, when using D. virilis gene sequences as an outgroup, for all variants that are apparently fixed between the two chromosomal backgrounds.
