In a way, the range of opinions by scientists who also identify as L.G.B.T.Q.
自我認(rèn)同也為L.G.B.T.Q.人士的其他科學(xué)家對該研究可謂眾說紛紜，一定程度而言，
underscores a central finding of the study: Sexuality is complicated.
這也凸顯出了該研究的一大核心發(fā)現(xiàn)：性取向是個復(fù)雜的問題。
The study analyzed the genetic data of 408,000 men and women from a large British database, the U.K. Biobank,
這一研究分析了英國生物銀行收集的來自40.8萬名男性和女性的基因數(shù)據(jù)，
who answered extensive health and behavior questions between 2006 and 2010, when they were between the ages of 40 and 69.
所有人都在2006年至2010年間，當(dāng)時他們的年齡都在40歲至69歲之間，回答過大量有關(guān)健康和行為的問題。
The researchers also used data from nearly 70,000 customers of the genetic testing service 23andMe,
研究人員還調(diào)用了基因檢測服務(wù)供應(yīng)商23andMe的近7萬名客戶的數(shù)據(jù)，
who were 51 years old on average, mostly American, and had answered survey questions about sexual orientation.
這些客戶的平均年齡為51歲，大多數(shù)都是美國人，都做過有關(guān)性取向的調(diào)查問卷。
All were of white European descent, one of several factors that the authors note limit their study’s generalization:
所有人都是歐洲白人的后代，不過，作者們認(rèn)為，這一點也限制了他們的研究的綜合性：
Trans people were not included.
跨性別人群沒有被納入考察范圍。
The researchers mainly focused on answers to one question:
研究人員主要關(guān)心的問題只有一個：
whether someone ever had sex with a samesex partner, even once.
是否和同性發(fā)生過性行為，哪怕只有一次。
A much higher proportion of the 23andMe sample — about 19 percent compared to about 3 percent of the Biobank sample —
相比之下，23andMe的樣本人群中匯報有過這一經(jīng)歷的人的比例要高得多——約為19%，而Biobank樣本的比例僅為3%——
reported a samesex sexual experience, a difference possibly related to cultural factors
這一差異可能與文化因素有關(guān)，
or because the specific 23andMe sexual orientation survey might attract more L.G.B.T.Q. participants.
也可能是因為23andMe的調(diào)查的性取向?qū)傩悦鞔_，因而吸引了更多的L.G.B.T.Q.人士參與調(diào)查。
Despite its limitations, the research was much larger and more varied than previous studies,
盡管該研究存在一定的局限性，依然比之前的研究廣泛豐富，
which generally focused on gay men, often those who were twins or were otherwise related.
因后者關(guān)注的重點一般為男同性戀，通常還是雙胞胎或有其他親屬關(guān)系的男同性戀。
Melinda Mills, a professor of sociology at the University of Oxford,
梅林達·米爾斯，牛津大學(xué)社會學(xué)教授，
who wrote a commentary that Science published alongside the study,
針對這一現(xiàn)象寫了一篇評論發(fā)表在《科學(xué)》期刊上，
said “Just the fact that they look at women is hooray.”
她表示：“該研究還關(guān)注到了女性，就這一點，就值得肯定了。”
There might be thousands of genes influencing samesex sexual behavior, each playing a small role, scientists believe.
科學(xué)家們認(rèn)為，影響同性性行為的基因可能有很多，每一種都只發(fā)揮了很小的作用。
The new study found that all genetic effects likely account for about 32 percent of whether someone will have samesex sex.
這項新的研究發(fā)現(xiàn)，一個人是否會有同性性行為，基因的作用可能占到了總影響因素的作用的32%。
