ABSTRACT Karyotypes and allozyme data for 32 genetic loci overwhelmingly support the conclusion that Aspidoscelis laredoensis is a diploid all-female species that had a hybrid origin between A. gularis × A. sexlineatus. Comparisons of allozymes in individuals representing three mother-to-daughter generations raised in the laboratory suggest that they reproduce by parthenogenetic cloning. In addition to two previously described morphotypes (pattern classes A and B) that occur in southern Texas, we report the existence of three all-female clonal lineages based on allozymes. Individuals of at least one of these lineages occasionally hybridize in nature with males of A. gularis, producing viable and healthy triploid offspring that can grow to adulthood, one of which herself produced an offspring in the laboratory and could have represented a new, clonal triploid species. The possibility exists that cloned offspring of triploid hybrids are present in South Texas and/or northern Mexico, awaiting discovery. These would represent a new species that would appear to be very similar to A. laredoensis.

德克萨斯州鞭尾蜥蜴之间的杂交：Aspidoscelis laredoensis 和 A. Gularis，以及杂种繁殖的注意事项

摘要 32 个基因座的核型和等位酶数据压倒性地支持 Aspidoscelis laredoensis 是二倍体全雌性物种，在 A. gularis × A. sexlineatus 之间具有杂交起源的结论。对实验室培养的代表三代母女的个体的同工酶的比较表明它们通过孤雌生殖克隆进行繁殖。除了发生在德克萨斯州南部的两个先前描述的形态类型（模式类 A 和 B）之外，我们还报告了基于等位酶的三个全女性克隆谱系的存在。这些谱系中至少有一个的个体偶尔会与 A. gularis 的雄性在自然界中杂交，产生可以生长到成年的可行和健康的三倍体后代，其中一个自己在实验室中产生了后代，并且可能代表一种新的、克隆三倍体物种。三倍体杂种的克隆后代可能存在于德克萨斯州南部和/或墨西哥北部，有待发现。这些将代表一个与 A. laredoensis 非常相似的新物种。
