>>108452237there is no gay gene.
but there are theory that gayness occurs if certain hormones are out of balance during fetal development.
they did a test on labrats.
In rats (and im guessing humans have a form of this) they have cells in the brain that determine sexuality. the bigger the cells the more they are attracted to females.
they found that if less testosterone was introduced to a rat fetus during development their sexuality cells in the brain were smaller and they had an attraction to males.
with the lab rats they found that the size of these sexuality sizes were irreversible once the rat was born. so being gay is irreversible... in rats at least.
if a women has many sons the youngest is the most likely to be gay because the fathers testosterone (produced by the feotus) is attacked but the mother immune system.
in short. If your having a boy stop drinking the onions.
i personally believe that being gay is a form of having an intersex issue. if an intersex issue is because the genitalia is ambiguous/does not match their chromosomes, often times because the wrong hormone is introduced during fetus development, then shouldn't being gay, if caused by the wrong hormone effecting a gendered part of the brain be considered an intersex condition.
