For the most part, science has had a pretty vague understanding of why people are gay: genetics. Hey, genetics explains practically everything else about the human condition, so it really only makes sense that it also covers your basic sexuality.
But delving deeper into the genetic component behind sexuality is a little trickier. Yes, genetics account for your basic, no-frills sexuality, but where do they come from? Why is it so wide-ranged to begin with? And is there a Darwinian reason behind all those pornos where everyone ejaculates into a giant martini glass and one person drinks it?
Well, it looks like science may have finally discovered how genetics come together to make people gay. Shockingly, it’s incredibly complex and incomprehensible.
Researchers from the National Institute for Mathematical and Biological Synthesis have said the genetics that makes a person more likely to be gay are passed from fathers to daughters and mothers to sons.

Gender-specific epi-marks are usually ‘erased’ from generation to generation, but when they do not and they pass from a parent to a child, it can result in homosexuality. [SOURCE]
