The question where does homosexuality originate is very controversial in a religious, political, scientific and moral way. This question may be answered as by nature or by nurture. Many testing demonstrates that the answer might probably be nature. There is a case of twin boys in which they have had the same nurture, and one of the twins plays with G.I Joes while the other twin plays with neo pets and Bratz dolls. This is called “Child Gender Non Conformity” this is when a child whose behavior is more typical of the other sex. This condition is more culturally due to the fact that within different cultures you can see different aspects that are considered masculine or feminine. It is not entirely environmental or entirely genetic. There are other scientists that believe that it may be hormonal because of tests done on rats. Because of the environment in the wound there are finding that prove that for every older brother a man has there is a 1/3 chance that he will be gay this is because the mother in the wound is making anti bodies for the Y chromosome in men but if the men is left handed there is no problem, he will not be affected by this, and this is not proved for lesbians, just gays. This factor is not proven to be true yet. There is much controversy with this subject of nature or nurture, but it is certain that homosexuality is usually not chosen.
