    In 1993 a region of the human genome called xq28 was linked to male homosexuality, and thecontroversial notion of a “gay gene” was born. Those research findings have not beenreplicated. But it was never going to be that simple: decades of genetic research have shown that almost every human characteristic is a complex interplay of genes and environmental factors. A new study, published in Science this week, confirms that this is the case for human sexuality, too.

    在1993年,人类基因组中被称作xq28的一部分,与男性同性恋联系在一起,与此同时,“同性恋基因”这个具有争议性的概念诞生了。这些研究成果并没有被复制。但这永远不会那么简单:数十年的基因研究表明几乎每个人格特质都是基因和环境因素间复杂的相互作用。一个发表于本周《科学》杂志上的新研究,证实人类同性恋就是如此。

    GWAS involves scanning a person’s DNA for tiny variations in the genetic code that correlate with a given trait. The participants were divided on the basis of whether they answered yes or no to the question “Have you ever had sex with someone of the same sex?”—a woolly proxy for sexual orientation, even in the absence of little white lies. The figures the GWAS produced, therefore, relate only to a single act, not to whether someone identifies as gay.

    in the absence of little white liesin the absence of:在没有……存在的情况下。white lie:善意的谎言,A "white lie" is a small, innocent lie that people tell for social reasons. If I didn't like your mother's cooking, but said I did, it would be a white lie.  People often hesitate to give truthful answers about sex--they might tell white lies to protect themselves from embarrassment, even in an anonymous survey.

    (关于为什么这个问题是性取向鉴别的模糊指标)So, there are two different reasons that the question is a bad way to identify sexual orientation. The first reason is that, because the question is about sex, there is a high likelihood that people will give incorrect answers--they will tell white lies. However, even if we assume that the respondents won't lie, a question about past behavior is different from a question about sexual orientation. Some people might have tried homosexual sex and discovered that they didn't enjoy it, or they might have experienced homosexual rape, or they might prefer heterosexual sex but be willing to engage in homosexual sex in unisexual environments like boarding schools, the military, or prison. Other people might desire homosexual sex, but not have had it yet. So, the answer to the question will only be loosely correlated with sexual orientation. It is a bad (aka "woolly") proxy for sexual orientation.【词组积累】

    identify ~ sb/sth (as sb/sth) 显示;说明身份to make it possible to recognize who or what sb/sth is. Someone identifies as gay说明某人是同性恋。【熟词僻义】

    一个全基因组关联研究,内容包含为了基因组中的一个与特定的特质相关的小变化而扫描一个人的DNA。根据参与者对问题“你曾经和同性发生过性关系吗?”的回答是“是”或“否”进行分组—一个衡量性取向模糊的指标,甚至是在没有谎言的情况下。因此,这个研究产生的结果,只与一个单一的行动有关,而不能确定某人是同性恋。

    The researchers found five genetic markers that were significantly associated with a reported homosexual act by one of the participants in the study. None of those markers was on the x or ysex chromosomes and their total combined effect accounted for less than 1% of the variance. This is because the behavior is the result of the aggregate effort of hundreds or thousands of genes, whose individual effects are infinitesimally weak. Totting up all the thousands of testedgenetic variants accounted for between 8% and 25% of the variation in people’s self-reportedhomosexual acts. These variants also overlapped with other traits, such as a smoking and an openness to new experiences.

    self-reported自述的【词汇积累】

    an openness tothere is an openness to sth对……持开放,接纳态度。【词组积累】

    通过研究中的一个参与者,研究人员发现五个遗传标志与报道的同性行为明显相关。这些标志都没有在X或Y性染色体上,而且他们所占的总的共同作用少于变异的1%。这是因为行为是几十万基因共同作用的结果,单个基因的作用无限小。将引起8%-25%人类自述的同性行为改变的数千个被测基因变异相加。这些变异也和引起其他特征的变异相重合,例如吸烟和接受新的体验。

    Interestingly, only about 60% of the genetic variants identified in the study were shared by both sexes. Most behaviors show more overlap between the sexes than this, intimating that male and female homosexuality, or at least sexual adventures, may be quite different. David Curtis of University College London notes that what overlap there is “suggests that there could be specific factors affecting same-sex attraction rather than simply being attracted to males versus being attracted to females.”

    overlap重叠部分

    intimateintimate作形容词有亲密的,密切的意思,这里作动词:(间接)表示;暗示to let sb know what you think or mean in an indirect way. 【熟词僻义】

    note特别提到;指明,表明【熟词僻义】

    有趣的是,研究中只有大约60%确认的基因变异是两种性别共同拥有的。大多数行为两性共有的变异重叠率比同性恋行为共有的重叠率更多,这暗示同性恋,或者至少是冒险性行为,可能与其他行为特征有着显著的不同。英国伦敦大学的David Curtis提出这里的基因重叠暗示可能有特定的因素影响同性吸引,而不是简单的被男性与被女性吸引。

    Yet the research only scrapes the surface of the mysterious depths of human sexuality.Unravelling these riddles will be difficult and will inevitably beget misconception and controversy. But at least this study should add weight to the view that non-heterosexualbehaviour is firmly within the normal, natural spectrum of human diversity and provide a firm foundation for future work.

    a firm foundation稳固的基础

    然而,这项研究仅仅只是触及了人类性行为神秘深处的冰山一角。解开这些谜题将会很困难,并且不可避免会引起误解和争议。但至少这项研究可以进一步证明非异性恋牢牢地植根于正常、自然的人类多样谱之中,并为未来的研究提供了坚实的基础。
