Homosexuality: Choice or genetic?
Homosexuality has become an important issue in our community creating much controversy. The liberal citizens of our country congratulate those who have made the hard decision to “come out.” The decision to be openly homosexual is hard for some because of the rare acceptance that they receive. Society has made it so hard for homosexuals to be accepted, given the discrimination and hate crimes against them. The rights that have been taken from homosexuals, such as marriage, have led to a quest for knowledge on the question of whether homosexuality is biological or simply a choice. Researchers and scientists have been working diligently to find the answer to this question. If homosexuality is proven to be biological, many doors could open for the homosexual community. The government and other institutions would not be allowed to discriminate on many issues because the fact that someone is homosexual is not his/her fault. Through my study of current research I believe that homosexuality is biological in origin and is not the decision of the individual.
Physical genetic traits are one reason I believe Homosexuality is biological in origin. Homosexuality is linked to the genetically determined finger length ratio. In people with homosexual preference, there is a tendency for the ratio to be lower than in heterosexuals of the same sex. Marc Breedlove, currently the Barnett Rosenberg professor of neuroscience at Michigan State, found no difference between the straight and gay men 's finger-ratios until he separated the men by birth order. Then his team found that gay males who had two or more older brothers had slightly lower ratios than those with no older (Sigesmund). The probability that a man has homosexual preference increases with the number of older brothers he has. Each older brother increases the odds by 1/3 – 1/2 (Pease and Bull).This effect focuses on the mother progressively building antibodies against an unknown male protein, more so with each son. By this
