New research suggests that homosexuality is passed from parents to opposite-sex offspring through epi-genetics
BY TRACY CLARK-FLORY
Researchers announced today that homosexuality isn’t strictly genetic. But before the homophobes break out their party hats to celebrate this as proof of same-sex attraction being “unnatural,” note that the study in the Quarterly Review of Biology argues that homosexuality is passed from parent to child.
The key here is epi-marks, which control how genes are expressed, and they just might explain the evolutionary stumper of why, if homosexuality is hereditary, it hasn’t been eliminated from the gene pool.
As a press release explains in almost comprehensible terms, the study finds “sex-specific epi-marks, which normally do not pass between generations and are thus ‘erased,’ can lead to homosexuality when they escape erasure and are transmitted from father to daughter or mother to son.”
U.S. News translates that: “A lesbian will almost always get the trait from her father, while a gay man will get the trait from his mother.”
