our best guess is that homosexuality is partly explained by genetics, not fully. there's lots of headlines saying "genetic link for homosexuality found", which is ambiguous, so it's an understandable mistake.

by partly, I mean that we've found larger genetic links between 'propensity to work hard', and for IQ, than we have for homosexuality.

in the say way, I think we have indeed found some manner of link between genetics and depression, but again, it's sort of a tenuous thing.

Human behavior can never be fully explained by genetics, but a lot of these studies conflate 'homosexuals' and 'men who have sex with men' and there might lie the ambiguity.
