Same-Sex Behavior Is Linked to Genetics, Study Finds

The broad international study of close to half a million people was published online in the journal 'Science.'. It found that while same-sex behavior was linked genetically, there is no single gene correlated to it. Rather, the study found that the genetic markers for same-sex behavior can found over a range of genes. Like most human behaviors, the markers are influenced by a myriad of both environmental and genetic factors. This means that genetic markers cannot be used to identify same-sex behavior in an individual. According to the study, predicting sexual orientation based on a person's genome is "practically impossible.". Complicated behavior, such as same-sex sexual behavior, is a compilation of genetics and the social environment. It’s not just one or the other, Melinda Mills, Professor University of Oxford, via 'The Wall Street Journal'. This new study provides even more evidence that being gay or lesbian is a natural part of human life, [and] also reconfirms the long established understanding that there is no conclusive degree to which nature or nurture influence how a gay or lesbian person behaves, Zeke Stokes, GLAAD CPO, via 'The Wall Street Journal'. Researchers of the study — one of the largest of its kind — have created a website called "Genetics of Sexual Behavior."
