Research into a possible genetic basis for homosexuality has suggested the role of an as yet undiscovered gene localized to the q28 region of the X chromosome. However, this suggestion is controversial for a number of reasons, and the matter is unlikely to be resolved without a considerable amount of additional research.
Keywords: sexual orientation; homosexuality; twins; Xq28
