you idiot, he means a gene that controls loveuality.
what?
genes don't work like that, genes have properties which are derived from a combination of your parents genes.
So for someone to be gay one of there parents would have to be gay or be a carrier for homoloveuality.
take biology before discussing this
basically for their to be a loveuality gene, being straight/gay would be a condition, which doesn't make sense because its just a part of one's personality.
also people seem to exclude the possibility of it not being a choice but just being a product of your environment like most other personality traits
