Question

Girls ________ are more likely to develop lesbian or bisexual orientations.

1) who are later in birth order
2) exposed prenatally to very high levels of androgens or estrogens
3) who have a higher-than-average number of older brothers
4) who are gender-atypical in dress or behavior

Answer 1

There is no scientific consensus regarding the exact reasons why individuals have certain sexual orientations. Research suggests that sexual orientation has genetic and biological components, but other factors mentioned in the question are not supported by evidence.

Step-by-step explanation:

According to current scientific understanding, there is no exact reason why an individual develops a specific sexual orientation. Research suggests that sexual orientation has genetic and biological components, including gene-level contributions and differences in brain structure and function among individuals with different sexual orientations. However, there is no evidence linking sexual orientation specifically to being later in birth order, prenatal exposure to high levels of androgens or estrogens, having a higher number of older brothers, or being gender-atypical in dress or behavior.
