Sexual orientation is completely determined by genetics. c. Homosexuality is caused by insufficient amounts of testosterone. d. Some biological factors are correlated with homosexual orientation.

Short Answer

Expert verified
d. Some biological factors are correlated with homosexual orientation.

Step by step solution

01

Evaluate Statement A

Statement A says that biological differences in the hypothalamus cause homosexuality. While there are some studies that show differences in the hypothalamus of homosexual people compared to heterosexual people, it is not definitive that these differences cause homosexuality. Therefore, statement A is inconclusive and not a complete summary of the research findings.
02

Evaluate Statement B

Statement B claims that sexual orientation is completely determined by genetics. However, research indicates that genetics may have a role, but it is not the sole determinant of sexual orientation. Environmental factors, for example, also play a role in determining sexual orientation. Thus, statement B is not correct.
03

Evaluate Statement C

Statement C suggests that homosexuality is caused by insufficient amounts of testosterone. This statement is not accurate, as research has not found a direct relationship between testosterone levels and sexual orientation. Some studies even found no difference in testosterone levels between homosexual and heterosexual men. Therefore, statement C is incorrect.
04

Evaluate Statement D

Statement D states that some biological factors are correlated with homosexual orientation. This statement is a more accurate summary of the research findings, as it is true that some biological factors, such as genetics, have been found to correlate with homosexuality. Multiple factors, including environmental factors, contribute to determining an individual's sexual orientation. Thus, statement D is the correct answer. The correct answer is: d. Some biological factors are correlated with homosexual orientation.
