Chromosome maps of the Siamese cobra chromosome 2, and Z and W chromosomes showing homologies with the chicken, zebra finch, and several other amniotes. This map was constructed using 43 BACs derived from the chicken and zebra finch. Locations of the BACs on Siamese cobra chromosomes are shown to the right of the chromosomes. Chromosome numbers indicate the chicken (Gallus gallus, GGA), the green anole (Anolis carolinensis, ACA), the bearded dragon lizard (Pogona vitticeps, PVI), the Japanese four-striped rat snake (Elaphe quadrivirgata, EQU), humans (Homo sapiens, HSA), the tammar wallaby (Macropus eugnii, MEU), the duck-billed platypus (Ornithorhynchus anatinus, OAN), the giant musk turtle (Staurotypus salvinii, SSA), the mexican musk turtle (Staurotypus triporcatus, STR), the Hokou gecko (Gekko hokouenesis, GHO), and the sand lizard (Lacerta agilis, LAG) showing partial homologies with the Siamese cobra chromosomes. Partial syntenies are shown using the same color. Chromosomal locations of genes in the amniotes were obtained from the following sources: G. gallus from Matsuda et al. [33], A. carolinensis from Alföldi et al. [12], E. quadrivirgata from Matsubara et al. [21], G. hokouenesis from Kawai et al. [10], P. vitticeps from Ezaz et al. [13], H. sapiens and M. eugnii from Grützner et al. [55], O. anatinus from Veyrunes et al. [15], S. salvinii from Kawagoshi et al. [5] S. triporcatus from Montiel et al. [56], and L. agilis from Srikulnath et al. [14]
