IS A PERSON ‘BORN GAY’, OR IS BEG GAY A LEARNED BEHAVR?

Beg gay is not a choice for people. What we do know is that there isn’t one sgle gene that explas homosexualy. The most nvcg data about the geic basis of homosexualy om lookg at tws.

Beg gay has a lot to do wh geics.

Some of the bt evince that homosexualy has a strong geic part om tw studi. Tw studi of homosexualy have shown that intil tws are about twice as likely to both be gay pared to aternal tws.

ARE WE BORN GAY?

This means that beg gay is partly geic, and not simply somethg that a person learns or choos. If the DNA sequence were the only thg termg whether someone is gay or not, we would expect intil tws to match 100% of the time.

If one tw is gay, the other is gay about 50% of the time as well. What other factors might fluence whether someone is gay? When lookg at large fai, scientists saw that men wh lots of olr brothers were more likely to be gay.

Men wh lots of olr brothers are more likely to be gay. Of urse, this isn’t the only environmental explanatn for how people are born gay – there are plenty of men wh olr brothers who are not gay.

THERE IS NO ‘GAY GENE.’ THERE IS NO ‘STRAIGHT GENE.’ SEXUALY IS JT PLEX, STUDY NFIRMS

And there are plenty of gay men wh no olr brothers! Even though the evince is pretty strong for homosexualy beg partly geic, some people don’t accept . The argument monly go: If gay men and women are ls likely to have babi, they won’t pass on their gen.

So any “gay gen” should disappear. Ergo, beg gay n’t be geic.

WHY ARE PEOPLE GAY? GAY BY CHOICE OR IS BEG GAY GEIC?

One possible explanatn is that the same gen that make a man gay n also make a woman more fertile.

The looked at the female relativ of gay men, both on the mother’s and father’s si.

This uld mean that there are some gen that are passed down om the mother’s si that make women more fertile and make men more likely to be gay. No matter why those gen are still around, we do know that beg gay is partly geic and partly termed before a baby is even born. Will our child grow up to be gay or straight?

WHAT DO THE BIBLE SAY ABOUT BEG BORN GAY?

But on the other, he totally wrtl wh the image produced by the ia that one might be "born gay, " of a ltle male neonate appearg wh illy pk diapers and graspg a Barbie doll.

Plörl pared self-clared homosexual or heterosexual inti adults to their memori of genr nformy childhood. First, by ncentratg on the left si of the graphs, the rear n see that there is a segment of adult gay men who remember beg highly genr non-nformg as kids. But there were a signifint number of genr-nformg men who, nohels, veloped a gay or bisexual inty adulthood.

Maybe we n agree that the image evoked by "born gay"—that ltle girl neonate appearg wearg overalls and graspg a toy tck—do not help thk through qutns of sexual sire and inty. There is no sgle gene rponsible for a person beg gay or a lbian.

SCIENTISTS MAY HAVE FALLY UNLOCKED PUZZLE OF WHY PEOPLE ARE GAY

The study of nearly a half ln people clos the door on the bate around the existence of a so-lled “gay gene.

ARE YOU BORN GAY OR IS A CHOICE? SCIENTISTS MIGHT HAVE FOUND THE ANSWER

In s stead, the report fds that human DNA nnot predict who is gay or heterosexual. It is worth keepg md that this study only vers some typ of sexualy — gay, lbian and cis-straight — but don’t offer many sights to genr inty.
