Quizplus · Accepted Answer

The Maxillofrontal Index (MFI) and Zygoorobitral Index (ZRI) are commonly used to determine the racial ancestry of a skull with a femur. A high MFI indicates a more projecting mid-facial region, which is seen more frequently in Native American populations. A low ZRI indicates a more rectangular (as opposed to triangular) shape to the orbit, which is also seen more frequently in Native Americans. The Alpha Index and Platymeric Index are not commonly used in ancestry determination.
