1) relaxed molecular clock
宽松分子钟
1.
It is emphasized herein that the integrative approach of fossil dates and the relaxed molecular clock techniques would yield a better picture of the evolutionary timescale or a more precise and more accurate phylochronograms for organism groups than if only fossil dates or only molecular timescales are considered.
分子钟估算分歧时间的技术在不断改进,目前常用的分子分歧时间估算法(宽松分子钟法,如贝叶斯法、补偿性似然法等)包容分子演化速率在谱系间和随时间的变化。
2) Eight minute width
8分钟带宽
3) molecular clock
分子钟
1.
The paper also exploits the research and application of phylogeography on fish and its prospects from the aspects of geographical isolation,population dispersal,gene flow,fauna division and molecular clock estimate.
还从地理隔离、种群扩散、基因交流、区系划分、分子钟估算等方面阐述了系统地理学在鱼类的应用研究现况和应用前景。
2.
With galliform/anseriform divergence time as anchor point, molecular clock of basal Phasianidae is sequentially calibrated using 10 cytochrome b protein complete sequences.
使用 10个细胞色素b蛋白质全序列对雉科基部类群的分子钟进行了顺序标定 。
3.
Based on genetic distances, molecular evolution rates established by the hypothesis of molecular clock can be used to deduce the origin or divergence time of different organism taxa.
分子钟研究为探究早期生命演化提供了一个新的途径 ,不仅可用来对基于化石记录的传统结论加以验证 ,同时对于化石记录不完整的生物类群起源历史的推测具有特殊意义。
4) Molecular clocks
分子钟
1.
Anatidae molecular clocks was calibrated with 2 consensus sequences which come from Chinese domestic geese and European domestic geese and 13 sequences obtained from GenBank.
8MYA)为锚定点，用顺序标定法标定鸭科鸟类分子钟的分析结果表明，用“1+2TiTv”分析得到的鸭科鸟类的分歧时间比较可靠；氨基酸序列用泊松校正模型和Γ模型估计的分类单元间的分歧时间则比较一致，表明氨基酸序列更适合用于鸭科鸟类分子钟的研究；用同一基因标定分子钟时，较长序列得到的结果标准误比较小；与核苷酸序列相比，氨基酸序列更适于用作分子钟的标定。
