Can a larvae develop into a different kind of bee depending on what they eat when the are larvae? Yes. Can they switch at any time after the larval stage, no. Is it even that simple for all other traits affected by epigenetics? No.


League Champs is trying to make a bogus point from an article detailing work he vaguely understands.

but external factors now seem to be more of a major contributor than the actual DNA.


The article discussed the importance of epigenetics as an indicator for the development of homosexual tendencies, not "external factors".

You seem to be fallaciously equating environmental factors to epigenetic regulation.

I am assuming that the study alludes to external factors that the parents passed on, then possibly reinforced in their child.


That is an astounding assumption...especially the second half.

Don't know this fella, but he seems to have at least some familiarity with genetics. Solid posts throughout.

I'm not equating anything. The authors have clearly stated it cannot be genetic
quote:

Scientists from the National Institute for Mathematical and Biological Synthesis say homosexuality seems to have an epigenetic, not a genetic link.

quote:

genetics - a branch of biology that deals with the heredity and variation of organisms

quote:

Epigenetics – how gene expression is regulated by temporary switches, called epi-marks

It is currently believed to occur in the womb, meaning an external (or environmental) factor caused it. The external factors have not been identified. It's the current theory. Theories change over time.

This never happened!! It's damn near all but fact that being gay is genetic. The stupidity of the people on this board scares me

Either way, its external forces at work. It boils down to a choice someone made at some point in your lineage.


Dammit, Mom- did you REALLY have to drink that Cosmo and watch "Priscilla- Queen of the Desert" before you knew you were pregnant with me?

Finally got time to read the links. It reeks of someone trying to get a government grant for quasi-science.

Edited to add: It was also mentioned that the study relied heavily on "Mathematical Models." You know- those things that tell us where hurricanes DON'T go!

re: So it turns out being gay is not in the DNA


quote:

According to the study, published online today in The Quarterly Review of Biology, sex-specific epi-marks, which normally do not pass between generations and are thus "erased," can lead to homosexuality when they escape erasure and are transmitted from father to daughter or mother to son.


If they escape erasure then they would be passed on to the child. If they are passed on to the child then that is a heritable trait. There is no "choice" involved.

What the authors are hypothesizing is that everyone has these modifications in our epigenome. When parents have a child the normal course of action is to erase these epigentic modifications and the developing fetus will modify their epigenome based on their gender. The authors also state that if these changes are not erased and imprinted onto the child then homosexuality can arise in certain cercumstances.

quote:

Sex-specific epi-marks stop girl fetuses from being masculinized when they experience atypically high testosterone, and vice versa for boy fetuses.


No where is there a choice.

Someone doesn't know what epigenetics are and is spouting off false info like he's an expert

Correcting epimarks are a "curable" condition...

Certain cancers brought on by this can be cured...


Would the gays want cured, if they could?

I encourage you to try to tell someone with prader willi their situation is controllable and not inherent

Epigenetics have more to do with what makes you than the actual base pairs themselves more than likely.

Epigenetics will be huge in the coming years. That's where most of the secrets are.

Explain the twins, and natural selection, then?

For you not to have a choice, it would have to be coded on your gene. They clearly said that it is not.

epi- in this instance mean "after." Epi-genetic usually means variation happens after the formation of the gene material. They currently theorize it happens in the womb, but if they are wrong ...
quote:

We predict where the epi-marks occur, we just need other studies to look at it empirically. This can be tested and proven within six months. It's easy to test. If it's a bad idea, we can throw it away in short order.

They can come back and say, nope its not genetically encoded in the womb.

So we now know for certain that its not genetic, and if further tests determine its not encoded while in the womb, what's left? Environmental factors, thats all thats left.
quote:

The epigenome is important because it is a primary location of gene-environment interactions; it can be altered by exposure to certain environmental stimuli. Environmental effects may be direct or indirect. For example:

An environmental agent, such as a chemical toxin, may enter the cells of a tissue and interface directly with the genetic material.
Alternatively, an environmental condition, such as chronic stress, may stimulate the body to produce its own intrinsic epigenetic factors.

These environmental modifications leave the DNA sequence unchanged, but interfere with the expression of that sequence (the transcription and translation processes). Scientists are still investigating the way that the epigenome affects gene regulation. However, we know that epigenetic factors may act on DNA, RNA, and proteins at any stage of the gene-to-protein pathway:

Meh...of course people have a choice whether or not to stick his meatrod in a poopchute.

To say otherwise means man lacks free will...

Sexuality will always be a mystery...I know flamboyant seemingly gay men that have loving wives and large families...sure, they might have been epimarked to be gay, but these dudes chose to be straight...AND vice versa..

To anyone with an understanding of science and genetics, this seems obvious. If homosexuality were genetic in nature, it would no longer be in existence, on account of the genes not being passed on from one generation to the next. It is a choice, always has been.
