Being gay is in the genes, claims study

A new study has revealed that being gay may be in the DNA and it's a person's biological makeup that drives him to homosexuality.

Researchers from the Chicago University looked at 400-plus pairs of gay brothers and found two distinct bits of genetic material that are linked to homosexuality, the Washington Times reported.

However, scientists have said that they don't know which of the specific genes in the two links of DNA are key to the formation and development of sexual orientation, but said that their findings add to a 1993 study that identified a supposed "gay gene,".

Michael Bailey from Northwestern University, Illinois, said that sexual orientation has nothing to do with choice and that the study has suggested that it's in the genes.

Bailey added that although the study could one day lead to a prenatal test for male sexual orientation, but it would not be very accurate, as there are other factors that can influence the outcome.
