There was no RS2 repeats unit in the control region, which indicated that repeat units had unimportant biological function in the mitochondrial genome. There were 4 bases mutated in the CSB?3 of this region exceeding other known Felidae by a long way.

• 在控制区中,没有发现RS?2重复序列,暗示了重复序列在线粒体基因组中可能没有重要的生物学功能,同时在控制区的CSB?3区存在4个碱基的变异,远远高于已知的其它猫科动物在此区域的碱基变异数量。
