?لا توجد صلة بين كروموسوم Xq28 و الشذوذ الجنسي.

Six years ago, molecular geneticist Dean Hamer and his colleagues announced that they had found a genetic link to male homosexuality–an as yet unidentified gene on the X chromosome (Science, 16 July 1993, p. 321). Now on page 665, a research team reports failing to find a link between male homosexuality and Xq28, the chromosomal segment implicated by Hamer’s study. In addition, other unpublished work does not provide strong support for a linkage. The authors of the Science paper say that, taken together, the results suggest that if there is a linkage it’s so weak that it’s not important and that researchers should be looking elsewhere for the genes that contribute to homosexuality!
