Question

Quizplus · Accepted Answer

There have been studies that have reported differences in brain structures in homosexual individuals, but size differences in the right brain hemisphere is not a consistent finding and cannot be considered as solid evidence for a biological contribution to sexual orientation. A and C are findings that do support a biological contribution to sexual orientation, as Simon LeVay found differences in the hypothalamus between homosexual and heterosexual men and X chromosome loci were identified as common in homosexual brothers. Twin studies (B) have also suggested that there is a genetic component to sexual orientation.
