Comparative analysis of the Indian cobra genome versus anole lizard genome. (a) In silico chromosome painting showing cross-species homology, confirming the similarity between chromosome 6 of lizards and chromosome Z of snakes. Different colors represent distinct chromosomes. (b) A dot-plot view of genomic comparisons indicating different evolutionary patterns, suggesting that chromosomal rearrangements, such as inversions, have reshaped snake sex chromosome evolution. Homology between both chromosomes Z and 6 is highlighted with a dotted box. (c) Distribution of genomic repeats on the Z chromosome of Indian cobra showing specific expansion of repeat elements, such as CR1.
