Base-pair substitution rates for the mitochondrial cytochrome beta gene of free-living, native populations of voles collected next to reactor 4 at Chernobyl, Ukraine, were estimated by two independent methods to be in excess of 10(-4) nucleotides per site per generation. These estimates are hundreds of times greater than those typically found in mitochondria of vertebrates, suggesting that the environment resulting from this nuclear power plant disaster is having a measurable genetic impact on the organisms of that region. Despite these DNA changes, vole populations thrive and reproduce in the radioactive regions around the Chernobyl reactor.
通过两种独立方法估计，乌克兰切尔诺贝利4号反应堆旁采集的野生本地田鼠种群线粒体细胞色素β基因的碱基对替换率超过每代每个位点10^(-4)个核苷酸。这些估计值比脊椎动物线粒体中通常发现的替换率高数百倍，这表明这场核电站灾难所造成的环境正在对该地区的生物产生可测量的遗传影响。尽管存在这些DNA变化，田鼠种群仍在切尔诺贝利反应堆周围的放射性区域繁衍生息。
