Throughout American society the topic of homosexual equality and marriage has been discussed beyond the point of surprise. Most consider homosexuality to be a choice, some consider it a gene that is passed down through birth and is a state of being directly from birth (or before). Robert Alan Brookey states, (page 27, paragraph 2) “Although his theory points to a biological cause, Ulrichs also believed that male homosexuality was a psychological condition. For example, he argued that the Urning’s female sex drive is complemented by a feminine psyche: “Distinct from the feminine persuasion of our sexual drive, we Urnings have still another feminine trait in us which, so it seems to me, offers the most positive proof that nature developed the …show more content…
“Kallman’s view of male homosexuality as a feminized condition follows a similar path. He claimed that male homosexuality could be attributed to an imbalance in the sex chromosomes, which creates a hormonal imbalance. Therefore, he believed the X chromosome to be dominant in the homosexual male. Although all men and women have at least one, the X chromosome is considered to be female because it is contributed by the mother. Kallman’s intersexuality theory posits that homosexuality occurs in men when the female chromosome dominates the male chromosome or, to put the argument in terms of heredity, when the mother’s genes dominate the father’s. Kallman’s theory replicates the Freudian paradigm of the dominant mother and the ineffectual father; He just mapped dominance onto the male homosexual’s genes. Implicit in Kallman’s theory is the background assumption that biological sex is dichotomous. Because the male homosexual departs from normal male sexuality, he also departs from his true physical sex. Because there are only two sexes, these departures can only be understood as a flight to the …show more content…
Consequently, some initial studies of the biology of homosexuality emerged out of the field of behavioral genetics and attempted to prove that homosexuality was inherited. Some earlier genetic studies (, for example, determined that sexually concordant identity (exhibiting homosexual or heterosexual preferences) is greater among monozygotic twins than it is among dizygotic twins. Because monozygotic twins share more genetic material than do dizygotic twins, their sexual concordance supports the claim that sexual orientation may be genetically
