Which bones are commonly used to determine the biological sex of an individual when you only have skeletal remains?Multiple Choicefemurtibiaulnapelvis

To determine the biological sex of an individual using skeletal remains, the following list explains the function of each bone type in sexual dimorphism:

1. Femur: While the femur has some sexual dimorphism, it is not typically the best indicator for sex determination on its own. The differences in size and robustness can be subtle.

2. Tibia: Similar to the femur, the tibia exhibits some variations between sexes, but it is also not the primary bone used for determining biological sex.

3. Ulna: The ulna, while it may show some differences, is usually not utilized as a reliable indicator for sex determination in skeletal remains.

4. Pelvis: The pelvis is the most reliable indicator of biological sex. It exhibits significant differences between males and females because of the adaptations for childbirth in females. Features such as the width of the pelvis, the shape of the pelvic inlet, and the subpubic angle are key indicators.

Final Answer

The correct answer is pelvis, as it provides the most accurate determination of biological sex in skeletal remains.
