Epigenetics Study Receiving International Media Attention


It has long been debated whether or not homosexuality is genetic. Now researchers at the University of Tennessee, Knoxville, say they’ve found a clue that may unlock the mystery. It lies in something called epigenetics—how gene expression is regulated by temporary switches. A working group at the National Institute for Mathematical and Biological Synthesis (NIMBioS), based at UT, used mathematical modeling that found the transmission of sex-specific epi-marks may signal homosexuality. Sergey Gavrilets, paper co-author, joint professor of math and ecology and evolutionary biology and NIMBioS’s associate director for scientific activities, has been interviewed by multiple media outlets worldwide about the research.
