Question

Quizplus · Accepted Answer

Physiological research related to sexual orientation has focused the most on finger-length patterns, specifically the ratio of the length of the index finger to the length of the ring finger (2D:4D ratio). It has been suggested that a lower 2D:4D ratio is associated with higher levels of prenatal androgens and a greater likelihood of being attracted to the same sex. Research on other characteristics such as body shape, voice tone, and amount of body hair have not yielded consistent or conclusive results.
