Mouse Homosexuality Linked to Genes

[JBeukema]

Sexual orientation cannot be tied to any one factor, but evidence supports the conclusion that environment has a greater impact than genes.

Most who possess a Y chromosome have a sexual attraction to to females. Most who do not, or whose Y chromosome is not active, have a sexual attraction to males.

This is true across species.

The only logical conclusion is that genetics are a dominant factor in sexuality and sexual preference.

 

[JBeukema]

Are you a man or a mouse?

So we can just discredit any/all scientific advancements made using animals as a model?

Absurd and you know it.

Why must you ruin everything?

 

[JBeukema]

Dogma means a belief that is not based on facts, and this certainly qualifies, as the Wiki article you linked to spells out. As of now no one understands exactly how genes produce anything, they just know that it happens. The central dogma of biology is that it occurs in the way you described, but it has not been proven.

Seriously, how many more patently false statements are you going to make about genetics in this thread?

We don't know how "genes" produce proteins? Really? We can't sequence DNA and tell which proteins will be produced? Really?

Ever hear of PCR or North,South, and/or West Blotting?

I wonder how he thinks we make GM foods


Now, what's this blotting stuff?

 

[JBeukema]

The gene that they targeted specifically removes a particular enzyme during the development of the mice. That may seem to you to be genetic, but it isn't.

What?

You are either so desperate to ignore this that you are being deliberately obtuse or you are blatantly ignorant of genetics and cell biology.

Even if it were to happen spontaneously, which is doubtful, it certainly would never account for the huge numbers of homosexuals that exist now and have existed forever.

Who said this was the only cause or factor?

Quick question for you people.....

Remember the African runner who ended up losing her medal? They thought she was on performance enhancers, as her testosterone levels were HUGE!

They then tested her genetically and found out that she's 60 percent male, the only thing female about her was her private parts.

Another example.........

Whenever someone goes to the sex change clinic, what is one of the first things they do? That's right......give them hormones of the gender that they want to become, resulting in dudes growing breasts and chicks getting facial hair.

What controls the hormones in the human body? That's right.....the glands that release them.

What causes those glands to form and find their right place? That's right......the DNA.

Yes, homosexuality is genetic, there are many places where it's been proven.

But, because we're more complicated physically than mice, we have more genes that determine how we're going to find a mate in life when we mature.

And the reason it scares all the homophobes? Most of 'em are closeted and are afraid that maybe they're really gay, which is why they react with such hate and fear to gays.

Straight males who are comfortable in their sexuality and know their sexual identity are RARELY ever homophobic.

Why? They know better, the homophobes are still wondering.

 

[AllieBaba]

yeah, and we all know that a huge percentage of lesbos are 60 percent male.

Do you have anything that's even slightly pertinent?

It's in my nature.

I am a blast at parties.

Homosexuality Linked to Genetics in Mice - TIME NewsFeed

Another of science's epic debates has finally been resolved: it turns out that homosexuality is genetic. (In mice, at least.)

According to a study published in the BioMed Central Genetics journalthis month, researchers from the Korea Advanced Institute of Science and Technology were able to prove a link between genetics and sexual preference in female mice.

The procedure involved removing the females' (conveniently-abbreviated) FucM genes, which caused their brains to be masculinized—essentially turning the mice into lesbians. Researchers reported that after the gene was removed the mice “exhibited a masculine behavior, such as mounting to a normal female partner as well as showing a preference to female urine.”

The peer-reviewed article can be found here.

While any researcher can tell you that mouse studies never directly apply to humans, this does prove that homosexuality can be induced by genetic manipulation of mammals.



To think, a simple genetic deletion can cause homosexuality in mice...fascinating.

So what relevance does this have to a search for homosexuality gene in humans? Well, technically none. The deletion of the FucM gene enabled the females' brains to extra estrogen exposure, but human brains are masculinized by progesterone.

this is like one of those cure for cancer or cure for aids stories that get misinterpreted in headlines in the mainstream media.'

there is no gene in the mice that made them homosexual. the study deals with genes that affect sexual preferences...I am surprised that Smeagle being a science type would miss all the nuance and 'stuff' .........

prison causes homosexual attraction too.

I'll just skip over your Kentucky windage attempt at biostatistics and comment on something you said that strikes me as interesting:

So the fact that homosexuality has existed forever suggests...........?

Listen you stupid twat, I was telling you of ONE CASE where this was tested and proven scientifically. According to the doctors, she is 60 percent male genetically.

But then again, what do I expect from some crazy bitch who uses circumcision as a way to tell human children from animal children?

Of course genotypic XY people that don't have the SRY gene are attracted to men.

Because they are females.

The female phenotype is the default embryonic developmental scheme.

I don't think there is any correlation with homosexuality and lack of an SRY gene.

Now, what's this blotting stuff?

Southern blotting sequences DNA, Northern blotting sequences mRNA, and Western blotting sequences the proteins from mRNA.

"homosexuality is genetic, there are many places where it's been proven. "

there has never been a credible argument for a homosexual gene. genetics may play a role, but as a deterministic qualifier, there is very little evidence.

She probably had androgen insensitivity syndrome.

[ABikerSailor]

Not a single gene, but if enough of them get turned from boy to girl (and you'd started building boy parts), the result will be a dude with a lot of estrogen and other traits.

Incidentally, the brain of a male straight and a male gay are very different. The gay males' brain is wired like a female straights brain.

 

[geauxtohell]

yeah, and we all know that a huge percentage of lesbos are 60 percent male.

Do you have anything that's even slightly pertinent?

Absurd.

You guys keep arguing around yourselves on this issue.

If "lesbos are 60 percent male" that means there would be something quantitative in the genotype that we could isolate that would show a 60% genetic difference between homosexual females and heterosexual females.

That's the very thing you are arguing against here.

In fact, you are disputing that one single gene can make a difference.

 

[ABikerSailor]

See.......that's the problem........everyone on the Christian side (and mostly devoid of science) are looking for a single gene that causes it.

It's not that........it's more like looking Nordic, you've got to have blonde hair, blue eyes, certain other types of features, etc.

Get one of 'em wrong (brown hair and green eyes), you're no longer Nordic, which means there is more than 1 gene that causes you to look that way.

Same thing with homosexuality, there isn't just 1 gene, but a specific set of them that contributes to their behavior.

We just haven't investigated the genome enough to understand it.

But......like I said, the homophobes are gonna fight this tooth and nail.

What you are talking about with genetic traits that are prevalent across a population is genetic linkage.

I suspect homosexuality is polygenic meaning that it's not a single gene that contributes to it, but rather several. I also believe that a certain component is nurture and not just nature.

That's just my belief. Unlike some on here, I won't try to pass it off as established science it is not.

That being said, I think it's interesting that a single gene is at issue here.

the results of the study vs the headline in the news.

the results I read do NOT support the headline: Homosexuality Linked to Genetics in Mice, but did support the line: were able to prove a link between genetics and sexual preference in female mice.

I wonder if a scientist can manipulate proteins on a gene that would make a mouse sexually attracted to leather or dead things?

there is more to sexual preferences than the terms homosexuality or heterosexuality suggest. I am sure there are genetic 'things' like proteins and such that get manipulated or massaged when sexual desires arise, but they do not dictate there must be a gene for preferences.

can't behaviors alter how genetic markers secrete or bond with other markers?

note: pardon the simplistic attempts at discussing genetic terms and science
