But the Y chromosomes differ in 30 percent of their DNA, meaning that these chromosomes are changing far faster in both species than the rest of the genome.
但是在Y染色体上却存在30%的DNA差别,这意味着两个物种的Y染色体比其它基因组变化得更快。
The team sequenced the same piece of DNA - 10,000,000 or so letters or 'nucleotides' from the Y chromosome - from two men separated by 13 generations, and counted the number of differences.
这个小组以相隔了13代的两个男性为测试对象,在其Y染色体相同区域上选取长约10, 000, 000核苷酸片段进行了测序,并计算了两者之间的差异。
Y chromosome is another focus of human evolutionary studies after mitochondrial DNA, which has also approved the "out of Africa" hypothesis.
染色体是继线粒体之后的研究人类进化的又一热点,通过对其上的多态性位点研究也证实了非洲起源说。
