It depends on how you’re looking at homosexuality; are you looking at it as sexual attraction, or as behaviour? If you’re talking about behaviour, then a lot of that is certainly environmental, e.g., if you’re raise a non-permissive location, you’re much, much less likely to engage in homosexual behaviour. But if you’re talking about sexual attraction, then it seems very unlikely that it could be anything other than primarily genetic.
I think that the fact that there’s a difference between how people act, versus how people feel, is what confuses so many people about being straight, gay, bisexual, transgender, etc., and why conservatives feel like there’s a ‘gay agenda’ to make kids gay (or trans) when a permissive society allows more people to act freely on the way that they feel.

There is evidence. See the fraternal birth order effect for just one example:

And scientist have created lesbian mice:

(Side note: it’s hilarious they shorthanded the enzymes to FucM)

today i learned. and it alignes so well with how in medieval times, only firstborns were expected to inherit the family farm and have children themselves. At least that’s how it was in many areas.
