通过两种独立的方法估计，在乌克兰切尔诺贝利反应器 4 号反应堆附近收集的自由生活的本地田鼠群体的线粒体细胞色素 b 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常见的估计值高出数百倍，这表明这次核电站灾难造成的环境对该地区的生物体产生了可测量的遗传影响。尽管DNA发生了这些变化，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。
BASE-PAIR substitution rates for the mitochondrial cytochrome b 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.
