养不养狗可能是你的基因决定的

If you had a dog growing up, there's a good chance you'll own one as an adult — but is that because of your experience or your genetic makeup?

如果你小时候养过狗，那很有可能成年后你还会养，那到底是因为你有养狗的经验还是因为你的基因造成的呢?

A team of Swedish and British scientists studied 35,035 sets of twins from the Swedish Twin Registry to find out. They compared that data to information about dog ownership from national dog registries and found a strong connection between genetics and the likelihood of owning a dog.

由瑞典和英国科学家组成的研究小组，从瑞典双胞胎登记处调取了35035对双胞胎的信息，又从国家狗狗登记处获取了有关狗狗所有权的信息，两者进行了比较研究，发现遗传学和养狗倾向之间存在着很强的联系。

"We were surprised to see that a person's genetic make-up appears to be a significant influence in whether they own a dog," says Tove Fall, lead author of the study, and professor in molecular epidemiology in an Uppsala University press release.

该研究的主要作者，乌普萨拉大学教授，《分子流行病学》作者Tove Fall说：“我们惊奇的发现，一个人的基因竟然对他是否养狗有着重大的影响。”

"As such, these findings have major implications in several different fields related to understanding dog-human interaction throughout history and in modern times. Although dogs and other pets are common household members across the globe, little is known how they impact our daily life and health. Perhaps some people have a higher innate propensity to care for a pet than others."

“因此，这些研究结果对于在历史和现代时期了解狗与人之间相互作用的几个不同领域具有重大意义。虽然狗狗和其他宠物一样，都是我们家庭的一员，但它们是如何影响我们的日常生活的，我们却不得而知，也许有些人天生就有养宠物的倾向。”

In the study, which was published in the journal Scientific Reports, the researchers conclude, "we show evidence of a strong genetic contribution to dog ownership in adulthood."

研究人员在《科学报告》上发表的这项研究中指出：“我们证明了基因对成年人养狗有着很强的遗传贡献。”
