the hammer of homosexuality

[TheRocketSurgeon]

That's the best concise summary of the state of the research I've seen. Kudos to D-News for getting it down to that level. I wouldn't have wanted to be the person who had to try to write a script for a piece explaining epigenetics for a TV crowd!

I seen somewhere but the  gist of it is if you get too much of the y chromosome you would  be born gay.
I was really trying hard to find that paper and study but this is best as i could find. But yeah people  you know
should really think before writing stupid stuff on the internet.

It's not the chromosome itself; it's the switching sequence of the genes that regulate hormone production timing and quantity. Other genes (called homeotic, or "hox", genes) which switch on the sequences of genes it takes to cause a fetus to develop will function differently depending on the hormone environment in which they find themselves, so the change in testosterone expression leads to changes in sexual centers of the brain and endocrine system, which seem to lead to a bisexual or homosexual orientation.

As pointed out in the video, it is not a sequence of actual DNA on the chromosome that does this, but a myriad of factors, which is why it has proven so hard to pin down. Unfortunately, people keep expecting there to be "a gay gene" in order for them to call it a natural phenomenon. That's just not the only way things work.

When we finished the Human Genome Project in 1999, we expected to find 100,000 genes for all the proteins and sequences we had already observed in the human body. Yet we only found 30,000 genes. It blew the researchers away because they had no explanation for how 30K genes could produce over 100K results. It turned out that the way in which those genes interacted with one another produced new protein-folding outcomes, depending on a number of factors. We thought we would "solve" genetics once we finished sequencing our genome; instead, we just opened a window into Level 2.

But the point is, it is clearly a natural phenomenon, found in almost every social animal species on the planet. And we're starting to get a pretty good image of how it occurs. Unfortunately, because there's no easy way to point to Gene #28,317 and say "that's it! That's the Gay Gene!", people are having a harder time seeing it as a natural phenomenon.
