— CPI GTG-banded karyotype and ideogram showing the physical location of FISH-anchored BAC clones, with sex-linked BACs in red, along with the homology of gene blocks to chicken (GGA) and human (HSA) chromosomes, depicted as colored blocks, and with the NOR location on CPI 14. “UL” indicates uncharacterized loci, that is, CPI BACs that did not map to annotated scaffolds and thus homology to GGA and HSA was precluded. Note that BACs 45D19, 35H18, 39D13 colocate with 39B2 in CPI-5, and BAC 6L20 shows some hybridization to this region as well, likely due to the presence of shared repeat sequences (see supplementary table S2, Supplementary Material online).
