Homosexuality Is Not Genetic, But It May Be Epigenetic

According to a new study done by an international group of scientists searching for the “gay gene”, epigenetics may explain why some people are attracted to the same sex.

The new theory is that homosexuality isn’t a result of genetics but a result of the external environmental factors of the genes during the fetal development process.

Epi-marks, temporary switches that decide how our genes are expressed, are usually not passed down from generation to generation.

However, it seems that sex-specific epi-marks do get passed down from either mother to son or father to daughter. This may explain why homosexuality tends to run in the family.

These epi-marks dictate how certain genes are expressed. While designed to protect the fetus from environmental influence, they also express genitals, sexual partner preference, and sexual identity.

Of course, this is still only a theory. More research must be done before anything conclusive can be settled upon.
