Research on the environmental conditions that influence sexual orientation indicates that

A) homosexuals are more likely than heterosexuals to have been neglected by their parents.
B) homosexuals are more likely than heterosexuals to have been overprotected by their mothers.
C) homosexuals are more likely than heterosexuals to have been raised in a father-absent home.
D) the reported backgrounds of homosexuals and heterosexuals are similar.

Research suggests that the reported backgrounds of homosexuals and heterosexuals are similar, indicating that environmental conditions may not play a significant role in determining sexual orientation. While studies have explored various factors that may contribute to sexual orientation, such as genetics and prenatal hormone exposure, there is not enough evidence to suggest that neglect, overprotection, or father absence are significant determinants of sexual orientation.
