Figure 1

Schematic diagram highlighting results of BAC clone assembly and annotation, FISH mapping, and evolutionary comparisons. For zebra finch, genes within boxes are linked in a single BAC contig. Contigs within dashed ovals are linked by known location within a single BAC but the order is uncertain. BACs that map to the same chromosome via FISH mapping in are within a solid oval (see also Figure 4 for FISH mapping results). For chicken boxes represent MHC-B and MHC-Y regions. For Xenopus boxes represent sequenced BACs whose chromosomal organization is unknown. For clarity, not all genes of the MHC are shown.
