Improved phylogenetic resolution for Y-chromosome Haplogroup O2a1c-002611

AbstractY-chromosome Haplogroup O2a1c-002611 is one of the dominant lineages of East Asians and Southeast Asians. However, its internal phylogeny remains insufficiently investigated. In this study, we genotyped 89 new highly informative single nucleotide polymorphisms (SNPs) in 305 individuals with Haplogroup O2a1c-002611 identified from 2139 Han Chinese males. Two major branches were identified, O2a1c1-F18 and O2a1c2-L133.2 and the first was further divided into two main subclades, O2a1c1a-F11 and O2a1c1b-F449, accounting for 11.13% and 2.20% of Han Chinese, respectively. In Haplogroup O2a1c1a-F11, we also determined seven sublineages with quite different frequency distributions in Han Chinese ranging from 0.187% to 3.553%, implying they might have different demographic history. The reconstructed haplogroup tree for all the major clades within Haplogroup O2a1c-002611 permits better resolution of male lineages in population studies of East Asia and Southeast Asia. The dataset generated in the present study are also valuable for forensic identification and paternity tests in China.

很有价值的新成果,恭喜传超博士的团队。不过传超博士依然未能摆脱汉藏分离的过时观念,就个人来说略感失望。尽管002611的某些支系在羌系民系中有极低的频度,但是这丝毫说明不了什么问题。更何况,现在的羌族与历史上的原羌有多少关系,我看这个要打一个大大的问号。

另外,本文再次证实002611在东南亚的存在,也进一步证实我根据兰海博士关于P164在东南亚扩散模式文章中的某些推测~

Congrats!
It would be perfect if the fig. 1 and table 1 were in the same fig. ---to save the time to go back and forth fitting the data to the tree.

There are seven subclades nested within O2a1c1a-F11, suggesting the expansion of this lineage is star-like7. Those subclades might have experienced different demographic ---------------------------------------------------

It is also need to mention that what is the 100% in Table1.

F377和F1316都是中原偏南方内陆,F377到F17只有两个SNP,无论F377是否测错为F17了,大的是时间段还是比较接近,F17各支加一起1.93%。
不知道微基因数据是不是北方更多,这里F1316是0.93%,F1316最高的是河南 ...

按图表,我这支在F11中人口最多啊,大数据,多样本下是否仍然成立啊?
