Research Finds Not One ‘Gay Gene,’ but a Multitude of Influences.
研究發(fā)現(xiàn)，同性戀并不是單個(gè)“同性戀基因”，而是多種因素共同作用的結(jié)果。
How do genes influence our sexuality?
基因?qū)ξ覀兊男匀∠蛴泻斡绊懀?/div>
The question has long been fraught with controversy.
這個(gè)問(wèn)題一直都充滿了爭(zhēng)議。
An ambitious new study — the largest ever to analyze the genetics of same-sex sexual behavior —
最近，一項(xiàng)宏大的研究——有史以來(lái)規(guī)模最大的一次分析同性性行為基因成因的研究——
found that genetics does play a role, responsible for perhaps a third of the influence on whether someone has same-sex sex.
發(fā)現(xiàn)，基因確實(shí)發(fā)揮了一定的作用：一個(gè)人是否擁有同性戀取向，基因發(fā)揮著大約三分之一的作用。
The influence comes not from one gene but many, each with a tiny effect —
但這種作用并不來(lái)自某一個(gè)基因，而是來(lái)自多個(gè)基因，每個(gè)基因的作用都很小——
and the rest of the explanation includes social or environmental factors —
剩下的還有社會(huì)因素和環(huán)境因素的影響——
making it impossible to use genes to predict someone’s sexuality.
由此，我們便無(wú)法單憑基因來(lái)預(yù)測(cè)一個(gè)人的性取向。
Benjamin Neale, a geneticist at the Broad Institute of M.I.T. and Harvard and one of the lead researchers on the international team, said
哈佛-麻省理工學(xué)院布洛德研究所的遺傳學(xué)家、該國(guó)際團(tuán)隊(duì)的帶頭研究員之一本杰明·尼爾表示，
“I hope that the science can be used to educate people a little bit more about how natural and normal same-sex behavior is,
“我希望能夠用科學(xué)來(lái)幫助人們了解同性戀是非常正常和自然的行為，
It’s written into our genes and it’s part of our environment.
“這種行為已經(jīng)刻在了我們的基因里，也是我們環(huán)境的一部分。
This is part of our species and it’s part of who we are.”
它是我們?nèi)祟惖慕M成部分，也是我們自身的組成部分。”
The study of nearly half a million people, funded by the National Institutes of Health and other agencies,
這項(xiàng)研究，由美國(guó)國(guó)立衛(wèi)生研究院及其他機(jī)構(gòu)聯(lián)合贊助，對(duì)近50萬(wàn)人進(jìn)行了研究，
found differences in the genetic details of same-sex behavior in men and women.
發(fā)現(xiàn)男性和女性在引發(fā)同性戀行為的基因細(xì)節(jié)上存在一定的差異。
The research also suggests the genetics of same-sex sexual behavior
該研究還表明，同性性行為的基因
shares some correlation with genes involved in some mental health issues and personality traits —
與一些涉及心理健康問(wèn)題和性格特征的基因存在一定的關(guān)聯(lián)——
although the authors said that overlap could simply reflect the stress of enduring societal prejudice.
盡管作者表示這一重疊不過(guò)是反映了長(zhǎng)期社會(huì)偏見(jiàn)帶來(lái)的壓力。
Even before its publication on Thursday in the journal Science, the study has generated debate and concern,
即便是在發(fā)表之前——該研究于周四發(fā)表于《科學(xué)》期刊——該研究就已經(jīng)引發(fā)了辯論和關(guān)注，
including within the renowned Broad Institute itself.
著名的布羅德研究所內(nèi)部就是如此。
Several scientists who are part of the L.G.B.T.Q. community there said they were worried the findings could give ammunition to people
該研究所的幾名L.G.B.T.Q.科學(xué)家擔(dān)心，這些發(fā)現(xiàn)會(huì)為那些
who seek to use science to bolster biases and discrimination against gay people.
試圖利用科學(xué)進(jìn)一步鞏固對(duì)同性戀者的偏見(jiàn)和歧視的人群所用。
One concern is that evidence that genes influence same-sex behavior
例如，他們擔(dān)心，基因影響同性戀行為的證據(jù)
could cause anti-gay activists to call for gene editing or embryo selection,
可能會(huì)導(dǎo)致反同性戀權(quán)利活動(dòng)人士呼吁科學(xué)家們進(jìn)行基因編輯或胚胎選擇，
even if that would be technically impossible.
盡管這一點(diǎn)在技術(shù)上并不能實(shí)現(xiàn)。
