Yet most ancestry testing only considers a single lineage, either the Y chromosome inherited through men in a father's line or mitochondrial DNA, which passed down only from mothers.

但是多数血统检测某个单一系统，或者是遗传自父亲的 Y 染色体，或者是由母亲遗传的线粒体 DNA。

Geneticists have recently studied the Y chromosomes, which are passed down from father to son, and they have estimated that 0.5 percent of the earth's male population, which equals to around 16 million males, are direct descendants from Genghis Khan.

那么，男性有一个X染色体和一个Y染色体，女性有两个X染色体。

One of these pairs, the sex chromosomes, determines person's biological sex and it can be composed of either two X chromosomes for females or an X and a Y chromosome for males.

Well if you're a male you get an " X" chromosome from your mother, but must receive a " Y" chromosome from your father.

男性会从母亲那得到其中一个 X 染色体，但是一定会从父亲那得到 Y 染色体。

All men inherit the Y chromosome not from mom and dad, but just from their dads.

所有男性的 Y 染色体不是来自父母，而是仅仅来自父亲。

When the sperm cell from your father which carries an 'X' or a 'Y' chromosome fuse with the egg from your mother, which carries an 'X' chromosome.

这时，一个来自父亲的，携带“X”或“Y”染色体精子会和来自母亲的，携带一个“X”染色体的卵子结合。

It's possible that about 0.5% of the men living today inherited their Y chromosome from a recent common ancestor, maybe Genghis Khan.

有可能，今天大约 0.5% 的男性从最近的共同祖先那里继承了他们的 Y 染色体，也许是成吉思。

And every male relative of that individual who's a first-degree relative has the same Y chromosome.

而这名男人的所有一级男性亲属都拥有相同的Y染色体。”

Humans have forty-six chromosomes of DNA, of which two help determine your sex, the " X" and the " Y" chromosome.

人类 DNA 有 46 条染色体，其中两条决定你的性别，X 与 Y 染色体。

For example, one recent study found a huge drop in Y chromosome diversity five-to-seven thousand years ago.

比如，最近一项研究发现，Y染色体的多样性在5000至7000年前大幅下降。

And even people with 'XX' Chromosomes that develop male genitals and characteristics, due to a piece of the 'Y' chromosome breaking off, and switching places to an 'X' chromosome.

甚至那些带有“XX”染色体的人也会发展出男性生殖器和特征，这是由于“Y”染色体的一部分断裂，并转移到“X”染色体上。

Including some on the " Y" chromosome, meaning they can be transferred from both the mother and the father.

其中包含一些在 Y 染色体上的基因，也就是说父母都有可能是你秃头的原因。

The male " Y" chromosome, on the other hand, does not have any color genes.

另一方面，公猫的 Y 染色体没有任何颜色基因。
