Twin studies and family trees provide strong evidence that sexual orientation is at least partly genetic. When one identical twin is gay, there is about a 20% chance that the other will be as well. But because this rate is not 100%, it is thought that environmental factors play a role as well.

There is increasing evidence of the influence of epi-marks as a genetic predisposition to homosexuality. The markers are passed on from the parent to the homosexual child. The epi-marks actually protect the parent but are passed on as a sort of genetic carry-over error to the child. The problem is that there is still variation - not all twins are gay. Thus there are also environmental and social factors. The most important years of sexual identity development are 1-4, (especially 1-2) not later. There is a lot of evidence to support the influence of family and social relationships, including trauma, abuse. Many gay persons (though not all) report childhood trauma; the rates of sexual abuse are higher than with straight persons, etc. There are multiple factors at work. We don’t know them all.In a 2012 paper, Rice and his colleagues suggested that such unerased epi-marks might lead to homosexuality when they are passed on from father to daughter or from mother to son. Specifically, they argued that inherited marks that influence a fetus’s sensitivity to testosterone in the womb might “masculinize” the brains of girls and “feminize” those of boys, leading to same-sex attraction.

And this is relative in that it goes to what causes crises in gender and sexual identity. The ideology that gender is what freely one determines it is is behind bills like this - we can talk about other theories on this thread I would think…how society handles this issue, how that affects us as a culture.
