虽然没有精确的统计研究(主要是没必要),但是很多数据发现,除去猩猩猴子等灵长类(96% - 99%与人类基因类似),第二位最接近人类基因系统的,还就是小白鼠。
小白鼠相对其他动物,更容易研究且更接近人类基因系统,连阿猫阿狗都自叹不如。这里有段引用:
“75% of mouse genes have equivalents in humans (source), 90% of the mouse genome could be lined up with a region on the human genome (source) 99% of mouse genes turn out to have analogues in humans (source)”
