我是C2b1a1a为什么改版之后变成了北方汉族

改版之前我记得是48%通古斯族群和25%北方汉族的
改版之后就变成了北方汉族变成了56% 通古斯变成了13%？
我是东北的蒙古族而且就连现在网站上对C单倍群的介绍中代表人种还是“蒙古族、澳洲土著和满族人”
那么这种改变的依据何在呢

改版后：

您好，东亚人群在近几千年甚至几百年才开始逐渐分化为不同的民族族群，各族群高度同源且存在一定程度的基因交流，所以汉族与蒙古语族群、通古斯语族群有很高的遗传相似性；由于蒙古语族和通古斯语人群还有来自西伯利亚的混血成分，而被认为是其区别于汉族而独有的特征成分，被计算为蒙古、通古斯祖源成分。汉蒙混合可能会导致我们计算低估了一些样本中的汉族成分而高估了一些样本的蒙古、通古斯成分，导致与传统认知不符。新版祖源在一定程度上修正了这一问题。

另外，Y染色体仅是一个父系标记，无法代表全基因组的多样性。

wegene的常染分析确实有问题。蒙古比例偏高。

看起来微基因的北方汉族标杆有巨大科学漏洞，如何能改进一下呢？

我也是C2b1a1a，类型和楼主一样，但是组成成分却差异很大，比如通古斯成分。这是怎么回事？
