Morphological, karyological, and allozyme analyses indicate that the parthenogenetic lizards Cnemidophorus neomexicanus and diploid C. tesselatus are hybrids formed, respectively, by crosses involving the bisexual species C. tigris and C. inornatus, and C. tigris and C. septemvittatus. Mitochondrial DNA, which is inherited maternally, was obtained from each of these species. Analyses of the mitochondrial DNA's and their restriction endonuclease digestion products by electron microscopy and agarose gel electrophoresis support the hybridization hypothesis by indicating that C. tigris (specifically the subspecies marmoratus) was the maternal parent species for both C. neomexicanus and C. tesselatus. Furthermore, these data imply that these two parthenogenetic species are younger than some races of C. tigris.
形态学、核型学和等位酶分析表明，孤雌生殖的新墨西哥鞭尾蜥和二倍体网纹鞭尾蜥分别是由涉及两性物种虎纹鞭尾蜥和无饰鞭尾蜥，以及虎纹鞭尾蜥和七纹鞭尾蜥的杂交形成的杂种。线粒体DNA是母系遗传的，已从这些物种中的每一个获取。通过电子显微镜和琼脂糖凝胶电泳对线粒体DNA及其限制性内切酶消化产物进行分析，表明虎纹鞭尾蜥（特别是亚种大理石纹鞭尾蜥）是新墨西哥鞭尾蜥和网纹鞭尾蜥的母本物种，从而支持了杂交假说。此外，这些数据表明这两个孤雌生殖物种比虎纹鞭尾蜥的一些种族更为年轻。
