Definition of "homosequential"

D. simulans, D. mauritiana and D. sechellia (which we will call “the siblings” when we do not need to distinguish among them) have homosequential polytene chromosome banding patterns differing from those of D. melanogaster by one long inversion on chromosome arm 3R and a few much smaller inversions.
