A specific part of the X chromosome called Xq28 had some influence on men’s sexual behavior. However scientists have not found concrete fundaments as to which of these number of genes in the region are involved in the determination of men sexual preference, or the number that lie in other sites within the genome. Researchers have said before how genes intertwined with men homosexuality may have endured evolution because they happened to make women who carried them more fertile. This could be the case for genes in the Xq28 region, as the X chromosome is passed down to men exclusively from their mothers (Sample 2). A scientist at the US national cancer institute, investigated the family histories of around a hundred gay men and found homosexuality was very likely and prone to be inherited. This study came up with the results that more than ten percent of brothers of gay men were gay themselves, in comparison to approximately three percent of overall inhabitants. On the other hand, uncles and male cousins on the mother’s side of the family led Hammer to have a closer look at the X chromosome.
