The material ancestry and approximate age of parthenogenetic species of Caucasian rock lizards ( Lacerta : Lacertidae)

摘要: Restriction enzymes were used to assay variation among mitochondrial DNAs from parthenogenetic and sexual species of Lacerta. This permitted identification the that acted as maternal parent various hybrid-parthenogenetic lineages. Lacerta mixta was for both L. dahli armeniaca, valentini uzzelli, raddei rostombekovi. The ancestry unisexualis is not clear. sample nairensis very similar one a population either could be unisexualis. all had low nucleotide diversity in absolute terms comparison their relatives. close similarity between mtDNAs respective ancestor provides strong evidence recent origin parthenogens. parthenogens indicates few females involved origins; parents armeniaca have come single population. patterns mtDNA are those Cnemidophorus Heteronotia, establishing geographically restricted origins general feature lizards.
