Not so much. A lot of "indicate" "may". That's hardly conclusive. They say so themselves.
"The paper, published today in Science, builds on results presented by the same team at a 2018 meeting. The published study emphasizes that the genetic markers cannot be used to predict sexual behavior."
Even if it were true, and 25% of the 3% of homosexuals in the population were genetically predisposed to it, that would be a very small number of the genuine article. Lotta posers.
