This condition, where an individual has two genomes present in the tissues of their body, is called chimerism.

这种情况下，一个人的身体组织中存在两个基因组，称为嵌合体。

Individuals with chimerism might have two-toned skin or hair, or two different colored eyes, but most are believed to have no visible signs of the condition.

嵌合体患者可能有两种色调的皮肤或头发，或两只不同颜色的眼睛，但据信大多数人没有这种情况的明显迹象。

Though there are very few documented cases of chimerism from an embryonic twin, we're all amalgams to some extent, carrying around the different genetic codes of our gut bacteria and even our mitochondria.

虽然很少有记录在案的双胞胎胚胎嵌合现象，但我们在某种程度上都是混合物， 携带着肠道细菌甚至线粒体的不同遗传密码。
