如果中国人在23的测试结果里出现南亚，中东，欧洲，非洲等成分，代表真的有来自那些地区，纯血统的祖先吗？

比如说我得23结果：
96.9%中国
0.5%韩国
0.6%东南亚
1.0%广泛东亚
0.3%广泛东亚和美洲
 
0.5%欧洲
0.1%东欧
不到0.1%广泛南欧
0.4%广泛欧洲
 
0.1%南亚
 
不到0.1%中非南非
 
 
如果有，比如说我0.5得比例，距离今天有多长时间？是否能以中亚或者少数民族来解释？
 
 
 
国外一个已经退休的教授 (Doug McDonald) 给我和我妈妈的23数据做了分析，没有任何非东亚因素。

Most likely fit is 80.3% (+- 14.2%) E. Asia (all S. Han Chinese)
and 19.7% (+- 14.2%) E. Asia (various subcontinents)
which is 100% total E. Asia-D. McDonald results
The following are possible population sets and their fractions,
most likely at the top
South_Han= 0.780 Mongolian= 0.220 or
South_Han= 0.525 North_Han= 0.475 or
South_Han= 0.932 Yakut= 0.068 or
South_Han= 0.758 Tu= 0.242 or
South_Han= 0.914 Buryat= 0.086 or
South_Han= 0.910 Mongola_Ch= 0.090
There clearly is nothing not from East Asia.
A custom fit to only that and Siberia gives
Tujia 0.7771 Tu 0.2229
North_Han 0.5352 Miao 0.4648
She 0.6212 Tu 0.3788
North_Han 0.3715 Tujia 0.6285
South_Han 0.5685 Yi 0.4315
South_Han 0.5948 Naxi 0.4052
all of which are perfect fits, so any or any average of rows, or any similar ethinc groupos will do.
YOU are from automated fit

all of which are perfect fits. You should look on the Web to see what tribes
we use in our fits are “appropriate” to you. Your chromosome plot is identical to the one I send.
