Genetic Diversity of mtDNA D-loop Polymorphisms in Laotian Native Fowl Populations
Native Fowl Genetic Variability mtDNA Maternal Origin
2016/5/16
Here, we studied the genetic diversity of native fowls in Laos by analyzing a mitochondrial DNA (mtDNA) sequence polymorphism. A 546-bp fragment of the mtDNA D-loop region was sequenced in 129 chicken...

In order to protect the genetic resource of native horse breeds, the genetic diversity of mitochondrial DNA (mtDNA) D-loop of three native horse breeds in western China were investigated. Forty-three ...
婆罗门牛mtDNA D-loop变异及其遗传背景
婆罗门牛 mtDNA D-loop多态性 遗传背景
2009/6/23
对10头原种婆罗门牛mtDNA D-loop全序列912 bp测序，婆罗门牛遗传多样性丰富，检测到的9种单倍型兼有瘤牛(B. indicus)与普通牛(B. taurus)的遗传背景，核苷酸变异率为6.25%，单倍型多态度为0.978±0.054，核苷酸多态度为0.014 30±0.008 68。所有单倍型聚为明显的两大分支，婆罗门牛的大部分单倍型为普通牛单倍型类群， 并占绝对优势(90%)，仅B...

新疆三种雅罗鱼 mtDNA D-loop PCR-RFLP 多态性 进化
2007/12/31
摘要用PCR-RFLP技术，对新疆分布的准噶尔雅罗鱼、贝加尔雅罗鱼和高体雅罗鱼的mtDNA D-loop高变区约827bp进行了扩增，用ScaI、HinfI、AluI、DdeI 4种限制性内切核酸酶对56个样本的扩增产物酶切和RFLP分析，共检测到6种单倍型。准噶尔雅罗鱼存在2种单倍型：BDAA和BDBA；贝加尔雅罗鱼存在3种：AAAA、ABAA和ACAA；高体雅罗鱼只有1种。初步认为，准噶尔雅罗...
