祖源这个依据是什么

顺天承命

我和我自己的还是二级关系，可以把数据传到魔方，看下有多少摩厘，父母子女3000以上，兄弟姐妹2000以上。我和我弟2300

这个是我家老大的，他和弟弟也是三级关系，和爷爷奶奶还有妈妈是二级关系，和我是三级😰

而且两兄弟自己都是三级关系

你和你母亲的关系对劲吗？亲子都应该显示一、（偶尔）二级关系，如果你和母亲的关系显示也不正常，那可能是你自己的数据/匹配有问题。如果你和自己母亲是一级关系，你孩子和你母亲是二级关系，反而你和孩子是三级关系。
嗯...
恕我直言，这像是叔侄关系

赶紧找客服确认一下数据

民間科學有個理論……但我還是想聽聽官方的科學解釋。

这个是我的，还有一个问题，我和我儿子显示是第三级关系，但是他们和我妈却是第二级，为啥

因为你儿子会有你老婆家族的祖源呀，不一定百分百遗传到你的。

Q: 祖源分析页面上的成分百分比是如何计算的？

A: 祖源成分分析是基于常染色体上的多态性位点（Single Nucleotide Polymorphisms, SNPs）进行计算的，具有比较强的群体特点，可以较好反应群体特征。因为常染色体存在同源重组现象，相应的祖源成分也会在一定范围内波动，所以从理论上讲，即使是亲生兄弟姐妹也可能没有任何相似性。
WeGene 目前是基于美国加州大学洛杉矶分校（UCLA）开发的ADMIXTURE软件进行祖源成分计算的从准确性和优化程度来说，这套软件在同类软件中都是较好的。我们使用的祖源成分数据集都是现代人的数据，所以计算结果反映的是和目标群体在基因组层面的相似性，并不涉及群体起源层面的解释。
