| 題目 | The evolutionary puzzle of homosexuality |
| 日期 | 20140218 |
| 簡介 | Since the early 1990s, researchers have shown that homosexuality is more common in brothers and relatives on the same maternal line, and a genetic factor is taken to be the cause. But since gay and lesbian people have fewer children than straight people, a problem arises: “How can a trait like male homosexuality, which has a genetic component, persist over evolutionary time if the individuals that carry the genes associated with that trait are not reproducing?” |

Homosexuality may be caused by chemical modifications to DNA

| 題目 | Homosexuality may be caused by chemical modifications to DNA |
| 日期 | 20151008 |
| 簡介 | A new study suggests that methylation patterns in DNA may influence sexual orientation. Over the past 2 decades, researchers have turned up considerable evidence that homosexuality isn’t a lifestyle choice, but is rooted in a person’s biology and at least in part determined by genetics. |

Scientists find DNA differences between gay men and their straight twin brothers

| 題目 | Scientists find DNA differences between gay men and their straight twin brothers |
| 日期 | 20151008 |
| 簡介 | For men, new research suggests that clues to sexual orientation may lie not just in the genes, but in the spaces between the DNA, where molecular marks instruct genes when to turn on and off and how strongly to express themselves. |

The gay gene myth has been exploded

| 題目 | The gay gene myth has been exploded |
| 日期 | 20190903 |
| 簡介 | The findings of a study of the genetic basis of homosexuality published last week in the journal Science explode the false narrative that being gay is an innate condition that is controlled or largely compelled by one’s genetic makeup. Rebutting decades of search by LGBT scientists for a “gay gene”, the study’s first author flatly concludes “it will be basically impossible to predict one’s sexual activity or orientation just from genetics”. |

If There Was a Gay-Straight Switch, Would You Switch?

| 題目 | If There Was a Gay-Straight Switch, Would You Switch? |
| 日期 | 20090414 |
| 簡介 | Is there a switch that turns you gay? Studies seem certain to bolster the growing scientific consensus that homosexuality is biological rather than learned. And they point to an answer to the lingering question of whether sexual orientation is hard-wired into the brain or whether it can be altered. But both sides of the debate agree that just because fruit flies and mice can easily switch from straight to gay does not mean that it is that easy for humans to make the same transition. |

What genetics is teaching us about sexuality

| 題目 | What genetics is teaching us about sexuality | |||
| 日期 | 20190829 | |||
| 簡介 | As researchers in biology and sociology who are also gay men, we have long wondered (and debated) whether sexual orientation has any biological basis.
A study published Thursday in Science looked at the DNA and sexual behavior of nearly 500,000 people… Researchers since the 1940s have described sexual orientation as a single trait that exists on a scale, ranging from “exclusively heterosexual” to “exclusively homosexual.” But the new study suggests that sexuality is more diverse than that — many different things, rather than one thing in greater or lesser degrees. But when the researchers tried to add up the contributions of each DNA variant they examined, they could predict less than 1 percent of the variation among study participants. |
