Two captive populations could n ' t be defined as separate evolutionary significant units ( esus ) because of lacking of genetic divergence between them , and should be considered as a single esu in the conservation of the species . by comparing the sequences of control region of mitochondrial dna from three species of crocodiles , it is revealed that the smallest genetic diversity exists between alligator sinensis and alligator mississipiensis . a portion of mitochondrial nd4 and cytochrome b gene of 3 species of crocodilian was sequenced 百年來關于揚子鱷的分類地位存在著很多爭議,本文利用測得的揚子鱷( alligatorsinensis ) 、暹羅鱷( crocodlylussiamensis )和灣鱷( crocodylusporosus )的mtdnand4和cytb基因序列,以及從genbank中獲得密西西比鱷、凱門鱷和海龜( cheloniamydas )的nd4基因和cytb基因相應片段,構建以海龜為外群的系統進化樹。
