Genetic Variation and Differentiation of Gekko gecko from Different Population
大壁虎不同地理居群的遗传变异与分化

Samples of Gekko gecko were collected from 12 areas of Guangxi China,Vietnam and Laos.Four hundred and twenty four base pairs of G.gecko mitochondrial Cyt b gene were sequenced and seven haplotypes were found.Gekko vittatus and Teratoscincus keyserlingii acting as outgroups,the phylogenetic trees of the G.gecko constructed using NJ and MP methods showed that the average genetic distances were:0.20%-1.20% between four haplotypes of black G.gecko from Guangxi China;0.50% between Vietnamese and Laotian red G.gecko;1.70% between Ningming and Vietnamese red G.gecko;2.20% between Guangxi and Laotian red G.gecko;8.60%-9.50% between black G.gecko from Guangxi and all red G.gecko.The genetic difference of black and red G.gecko reached the species or subspecies differentiation.
