Which characteristic is used to infer gender from the pelvis?

• A. The female pelvis is wider and flatter because of the birth canal.
• B. The pelvis has a large brow ridge
• C. The pelvis cannot indicate gender
• D. The pelvis color identifies gender

Answer: (A)

Understanding how the pelvis differs between sexes is key: the female pelvis is built wider to accommodate childbirth, with a broader pelvic inlet and a wider angle at the pubic arch. This broader, lighter geometry is the main clue used to infer gender from pelvic bones. So the statement that the female pelvis is wider and flatter because of the birth canal captures that distinguishing feature investigators rely on. The brow ridge belongs to the skull, not the pelvis, so it isn’t used for pelvic gender assessment. Pelvic color isn’t a reliable indicator, and it is possible to infer gender from pelvic morphology, so saying the pelvis cannot indicate gender isn’t correct.
