双语：女人选男人千奇百怪的标准(图)

　　If you have ever been attracted by a person's scent, it may be their genes you smell. Researchers believe that women can identify men based on differences as small as a single gene.

　　如果你曾经被某人的气味所吸引，实际上你闻到的是他们的基因。研究人员认为，女人能在一个单基因的基础上辨别男人之间的差别。女人根据小到单基因的差别就能辨别男人的不同。

　　In the most recent issue of Nature Genetics scientists look at the link between women's preference for the odors men give off and a group of genes called the Major Histocompatibility Complex (MHC)--which are an important part of the body's immune response.

　　在最新出版的一期《自然遗传学》杂志上，科学家阐述了女性对男性发出气味的喜爱与主要组织相容性复合体(MHC)这组基因之间的关系。MHC是人体免疫系统反应的重要组成部分。

　　A group of 49 women were asked to smell 10 boxes which contained pieces of T-shirts that had either been worn by men or contained a familiar household odor such as bleach or clove.

　　让受试组的49位女士闻装有男人穿过的衬衫或含有家常气味如漂白剂味或丁香味的10个盒子。

　　The men who had worn the T-shirts were selected based on their MHC genes, and were told to sleep in the shirt for two consecutive nights while avoiding other scents entirely, such as colognes and even contact with other people.

　　提供自己穿过衬衫的男子是按他们MHC基因选出来的，他们连续两夜都穿着这件衬衫睡觉，其间完全避开其它气味，如古隆

　　The women were then asked to rate each scent based on their familiarity, intensity, pleasantness, and spiciness, as well as choose the one odor which they would choose if they had to smell it all the time.

　　然后，要求女士们依据自己熟悉、强烈、愉悦和馨香的感受，将闻过的气味分类，并从中挑一种她们终身都能够接受的气味。

　　"A clear pattern emerged," said Dr. Carole Ober, co-author of the study and a geneticist at the University of Chicago. "The women did not choose scents of men with genes totally similar to their own, or totally dissimilar to their own. They chose men with an intermediate level of difference."

　　“一种清晰的分类模式出现了，”该项研究的合作者，芝加哥大学的遗传学家Carole Ober博士说。他说：“受试女士没有选择基因完全与自己相似或相异男人的气味，而是选择了有适度差别的男人气味。”

　　"The real surprising thing is that there was something special about paternally from one's father inherited genes," said Wayne Potts, an expert in the area of MHC research at the University of Utah.

　　犹他大学专门研究MHC的专家Wayne Potts说：“真正令人惊奇的是该研究结果与父系遗传基因有特殊关系。”
