Martin Ingvar, a professor of neurophysiology at Karolinska Institute, said the results were "very exciting."

　　卡羅林斯卡學(xué)院的神經(jīng)生理學(xué)教授馬丁.英格瓦說(shuō)，研究結(jié)果十分“令人激動(dòng)”。

　　"These are original findings which shed light on the fact that all of our behaviours are influenced by both nature and nurture. Even complex, cultural social phenomens such as marriage are influenced by a person's genetic make-up," Ingvar said.

　　他說(shuō)：“這些最新發(fā)現(xiàn)讓我們認(rèn)識(shí)到，人的所有行為都受到先天和后天兩大因素的雙重影響。即便是婚姻這種復(fù)雜的文化社會(huì)現(xiàn)象也受到人基因組成的影響。”

　　The same gene has previously been linked to monogamous behaviour in male voles, a mouselike rodent.

　　此前有研究發(fā)現(xiàn)，334型等位基因與雄性田鼠對(duì)配偶的忠貞度有關(guān)。

　　The results of the study were published Tuesday in the US scientific journal Proceedings of the National Academy of Sciences (PNAS).

　　該研究結(jié)果于本周二在美國(guó)美國(guó)國(guó)家科學(xué)院院報(bào)上發(fā)表。
