gay genes

so my sister was doing some research on homosexuality and shit to try to prove to our parents being lgbtq+ isn't a choice but something you're born with and apparently from the articles she read scientist are trying to find out if being homosexual or trans is a genetic thing or some shit and how it can be passed down
