Excerpt from Dr. Whitehead’s article on mygenes.com: “…There have been numerous attempts within at least 13 different research fields to show a strong biological basis to homosexuality and all have failed. This new field – epigenetics – will probably join them. The authors make a good case that epigenetics should be included in the mix of factors contributing to homosexuality. I agree, but believe it will prove to be a minor contributor only, along with many other minor contributors.”

“Epigenetics is control of genetic expression by factors other than the genes. These factors may be pre-natal or post-natal (occurring at any time of life), often coming from the exterior environment, both biological and social. Epigenetic marks (changes in protein configurations around the DNA) can also be passed on to descendants – but only to some extent.”
