我是C2b1a1a為什么改版之后變成了北方漢族

改版之前我記得是48%通古斯族群和25%北方漢族的?
改版之后就變成了北方漢族變成了56% 通古斯變成了13%？
我是東北的蒙古族而且就連現在網站上對C單倍群的介紹中 ?代表人種還是“蒙古族、澳洲土著和滿族人”
那么這種改變的依據何在呢

改版后：

您好，東亞人群在近幾千年甚至幾百年才開始逐漸分化為不同的民族族群，各族群高度同源且存在一定程度的基因交流，所以漢族與蒙古語族群、通古斯語族群有很高的遺傳相似性；由于蒙古語族和通古斯語人群還有來自西伯利亞的混血成分，而被認為是其區別于漢族而獨有的特征成分，被計算為蒙古、通古斯祖源成分。漢蒙混合可能會導致我們計算低估了一些樣本中的漢族成分而高估了一些樣本的蒙古、通古斯成分，導致與傳統認知不符。新版祖源在一定程度上修正了這一問題。

另外，Y染色體僅是一個父系標記，無法代表全基因組的多樣性。

唏噓的NTRK2基因

wegene的常染分析確實有問題。蒙古比例偏高。

酷酷的COBL基因

看起來微基因的北方漢族標桿有巨大科學漏洞，如何能改進一下呢？

我也是C2b1a1a，類型和樓主一樣，但是組成成分卻差異很大，比如通古斯成分。這是怎么回事？
