摘　　要：为了明确密点麻蜥(Eremias multiocellata)与荒漠麻蜥(Eremias przewalskii)2个物种间的基因渐渗问题,基于形态学研究方法,对采自10个样点的麻蜥样本进行形态鉴定,再进行样本形态可量性状的单因素方差分析以及主成分分析.结果表明,在密点麻蜥与荒漠麻蜥分布重叠区所采集的杂交个体,有与密点麻蜥相似的眼斑、背部斑纹,且其生殖方式也与密点麻蜥相同为卵胎生;但8个形态可量性状单因素方差分析与主成分分析的结果则表明,杂交个体与荒漠麻蜥间不存在极显著性形态差异,表明密点麻蜥与荒漠麻蜥之间存在一定渐渗杂交.In order to clear the hybridization between Eremias multiocellata and E.prezewalskiis,we distinguish the samples from ten locations and use the one-way ANOVA and the principal component analysis from morphological view.The results show that the hybrids which from overlapping areas of E.multiocellata and E.przewalskiis,are similar in the eye spots and the black stripes,as well as the same reproductive mode to E.multiocellata.However,the results of the one-way ANOVA analysis and the principal component analysis with 8 morphological traits show that there is no significant morphological differences between the hybrids and E.przewalskiis.The introgressive hybridization is morphologically verified between E.multiocellata and E.prezewalskiis.
