基因相似更容易成为夫妻

美国哥伦比亚广播公司:一项新的研究显示,基因相似更容易成为夫妻.行为科学家将800对夫妻的DNA与随机配对的人进行比较厚得出这一结论. CBS News reports that new research finds that people tend to pick spouses whose genetic profile shares similarities with their own. The effect is subtle, but it's important to understand that mating isn't truly genetically random, researchers report in the journal Proceedings of the National Academy of Sciences. They write the genetic effect might even signal or contribute to social inequality. The current U.S. social system might inadvertently sort people by genetics, for example, or contribute to schisms seen at the level of our very DNA.
