Synteny analysis between the Indian cobra and the prairie rattlesnake genome revealed large syntenic blocks within macro, micro, and sexual chromosomes. This study allowed the observation of chromosomic fusion and fission events that are consistent with the difference in chromosome number between these species. For example, chromosome 4 of the Indian cobra shares syntenic regions with chromosomes 3 and 5 of the rattlesnake genome, indicating a possible fusion event. Besides, chromosomes 5 and 6 of the Indian cobra are syntenic to rattlesnake chromosome 4, indicating a possible fusion event between these chromosomes.
