@Royal,You this ignorant autistic dolt, do you have a recurring urge to be silly? dont twist my words. if you must quote me, dont cherry pick. this is what i said;

joudini:
Although genetics play a large role in the behaviour of organisms, it is the combination of genetics with what an organism 'experiences' - the environment, that determines the ultimate outcome.

joudini:
How do you get NATURALLY BORN WITH GENES that genetically steer you into ruthless killing without environmental interference?

Autistic dolts like you make people agitate for a read-only internet. This is what wikipedia says about epigenetics;

wikipedia: In biology, and specifically genetics, epigenetics is the study of changes in gene expression or cellular phenotype, caused by mechanisms other than changes in the underlying DNA sequence – hence the name epi- (Greek: επί- over, above, outer) -genetics, some of which are heritable.

It refers to functionally relevant modifications to the genome that do not involve a change in the nucleotide sequence. Examples of such modifications are DNA methylation and histone modification, both of which serve to regulate gene expression without altering the underlying DNA sequence. These changes may remain through cell divisions for the remainder of the cell's life and may also last for multiple generations. However, there is no change in the underlying DNA sequence of the organism;[1] instead, non-genetic factors cause the organism's genes to behave (or "express themselves" differently

I never said environmental factors alone is responsible. Now read what these credible sites say about homosexuality and epigenetics;
Science daily:Epigenetics May Be a Critical Factor Contributing to Homosexuality, Study Suggests- Epigenetics -- how gene expression is regulated by temporary switches, called epi-marks -- appears to be a critical and overlooked factor contributing to the long-standing puzzle of why homosexuality occurs.
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. In the current study, researchers from the Working Group on Intragenomic Conflict at the National Institute for Mathematical and Biological Synthesis (NIMBioS) integrated evolutionary theory with recent advances in the molecular regulation of gene expression and androgen-dependent sexual development to produce a biological and mathematical model that delineates the role of epigenetics in homosexuality. read the full article here http://www.sciencedaily.com/releases/2012/12/121211083212.htm

What The Scientist say; [b]Researchers looking for a genetic signature of homosexuality have been barking up the wrong tree, according to a trio of researchers in the United States and Sweden. Instead, the scientists posit, epigenetic influences acting on androgen signaling in the brain may underlie sexual orientation. In a paper published last week (December 11) in The Quarterly Review of Biology, they propose a model describing how epigenetic markers that steer sexual development in males could promote homosexual orientation in females, and vice versa. The scientists offer their model to explain both the tendency of homosexuality to run in families, and the fact that so far no “homosexual gene” has been identified.[/b]full article http://www.the-scientist.com/?articles.view/articleNo/33773/title/Can-Epigenetics-Explain-Homosexuality-/

Fox news; [b]Epigenetics are heritable changes caused by factors other than DNA. Instead of traits getting passed down through the genes, epigenetic change happens because of the way genes are regulated, or turned on and off.

These genetic regulators may be the reason homosexuality persists in nature despite the fact that gay people are less likely to reproduce, suggests the new study published in the journal The Quarterly Review of Biology.

Time; Researchers at the National Institute for Mathematical and Biological Synthesis (NIMBioS) think they may have an answer. It’s not in written in our DNA sequence itself, they suggest, which explains why scientists have failed so far to find “gay genes,” despite intensive investigations. Instead, it’s written in how our genes are expressed: that is, in certain modifications to how and when DNA is activated. These changes can have environmental roots, so are not normally permanent enough to be passed from parent to child. But occasionally, they are.

“It’s not genetics. It’s not DNA. It’s not pieces of DNA. It’s epigenetics,” says Sergey Gavrilets, a NIMBioS researcher and an author on the paper that outlines the new theory of homosexuality, published in The Quarterly Review of Biology. “The hypothesis we put forward is based on epigenetic marks,” he says.

Wikipedia again; A 2010 study of all adult twins in Sweden (more than 7,600 twins)[8] found that same-sex behavior was explained by both heritable factors and individual-specific environmental sources (such as prenatal environment, experience with illness and trauma, as well as peer groups, and sexual experiences), while influences of shared-environment variables such as familial environment and societal attitudes had a weaker, but significant effect. Women showed a statistically non-significant trend to weaker influence of hereditary effects, while men showed no effect of shared environmental effects. The use of all adult twins in Sweden was designed to address the criticism of volunteer studies, in which a potential bias towards participation by gay twins may influence the results (see below).

Overall, the environment shared by twins (including familial and societal attitudes) explained 0–17% of the choice of sexual partner, genetic factors 17–39% and the unique environment 61–66%. The individual's unique environment includes, for example, circumstances during pregnancy and childbirth, physical and psychological trauma (e.g., accidents, violence, and disease), peer groups (other than those shared with a twin), and sexual experiences. In men, genetic effects explained 0.34–0.39 of the variance, the shared environment 0.00, and the individual-specific environment 0.61–0.66 of the variance. Corresponding estimates among women were 0.18–0.19 for genetic factors, 0.16–0.17 for shared environmental, and 0.64–0.66 for unique environmental factors. full article; http://en.wikipedia.org/wiki/Biology_and_sexual_orientation

All l see evidence for is that you are a piece of biased filth, who is an unfortunate statistic to the wrong stereotype that blacks dont read. the more l read your ramblings, the more l realise they are spouts originating from the dark spectre of a fevered mind.

Don't ever let me catch you spreading falsehood and uncited rants anywhere l might pass. Don't ever mislead and misinform impressionable minds and folks who might not know no better. you this intellectual cripple, cripples don't kick knowledge. What an ignorant clusterfuck!
