Which pelvic characteristics are typical of female sex determination?

• A. Narrow subpubic angle, and a narrow pelvic inlet
• B. Wider subpubic angle, broad pelvic inlet, and wide circular opening
• C. Deep greater sciatic notch and narrow pelvic inlet
• D. Very small pelvic opening

Answer: (B)

Pelvic morphology shows clear differences between sexes because the pelvis is adapted for childbirth. In females, the pelvis is wider and more open to accommodate a baby. The subpubic angle is notably wider, creating a broader pubic arch. The pelvic inlet is also broader and more circular, giving a rounder opening. When you see a combination of a wide subpubic angle with a broad, round inlet, that pattern fits the female pelvis best and is most informative for sex estimation. Patterns like a narrow subpubic angle with a narrow inlet point toward male anatomy, and a very small pelvic opening aligns poorly with female morphology.
