THE 'GAY GENE' IS A TOTAL MYTH, MASSIVE STUDY CONCLUS

For example, one may be straight while the other is gay. In s like this, some might argue that perhaps both tws are actually gay, but one jt hasn’t e out yet. In a study where scientists looked at the sexual aroal patterns of intil tws wh different sexuali—specifilly, where one was gay and the other was straight—they found that gay tws monstrated more genal aroal rponse to same-sex imag, whereas straight tws monstrated more aroal rponse to oppose-sex imag [2].

In theory, this means two people uld rry “gay gen, ” but both of them wouldn’t necsarily be gay pendg on certa environmental factors.
