Comparing with the complete nucleotide sequences of the mitochondrial genome of other crocodiles, no variation on gene arrangement or quantity was found in the mtDNA of Crocodylus niloticus, however, the control region varied greatly. In addition to the analyses of complete sequences, partial sequences of 12S rRNA, 16S rRNA and Cyt b gene from other 13 crocodile species were combined and analyzed. We attempted to diagram phylogenetic relationships among crocodile species to provide convenience for following research.展开更多
