Is homosexuality genetic or psychological

That’s the first thing you need to know about the largest genetic investigation of sexuality ever, which was published. “GAY GENES” New research has uncovered DNA differences linked to same-sex sexuality in both men and women. Those genetic tweaks don’t predict who is likely to be gay. Controversial results released in suggested a genetic link between bisexuality and risk-taking, but many researchers gay dna flaws in the methodology.

Like size or intelligence, sexual attraction isn't dna by one gene alone but is instead the result of the complex interplay between multiple regions of the genome and hard to pin environmental factors. That's the conclusion of an analysis conducted on half a million DNA profiles as gay dna of a giant study by researchers in Europe and the United States published in the influential journal Science on Thursday.
