Integrated BAC-based physical map of the Drosophila buzzatii genome. (We consider the cytological map to be a kind of physical map.) Vertical lines indicate the relative position of the 427 BAC clones that produced a primary hybridization signal and represent 181 contigs. Singletons are represented as discontinuous vertical lines. Clone names are shown above the chromosomes. Clone names separated by a bar were hybridized individually. Clone names with an asterisk indicate that two or three clones were hybridized as a mixture. The contigs to which the hybridized clones belong are represented by short horizontal segments below the chromosomes along with the contig number. The length of these segments is roughly proportional to contig size. See Supplemental Table S2 for details.
