Additional file 2: of Chromosome map of the Siamese cobra: did partial synteny of sex chromosomes in the amniote represent “a hypothetical ancestral super-sex chromosome” or random distribution?

Figure S2. Cytogenetic map of the Siamese cobra (Naja kaouthia), which shows chromosome homologies with chicken and zebra finch. This map was constructed with 25 chicken and zebra finch BACs mapped on the Siamese cobra macrochromosomes. Locations of BACs are shown to the right of the Siamese cobra chromosomes. The chromosome numbers show the chromosomes of the chicken (Gallus gallus, GGA) and zebra finch (Taeniopygia guttata, TGU), which show homologies with the Siamese cobra chromosomes. (JPG 118 kb)
