Skeletal Sexing

1. procedure by which skeletal remains can be identified as to sex. The best source for identification is the adult pelvis because it is highly sexually dimorphic. Differences between males and female pelves include the shape of the obturator foramen, angle of the pubic arch, shape of the pelvic inlet, width of the greater pelvis, acetabulum, and several other features. The skull can also be used for sexing in that males tend to have more heavily built (i.e. more robust) skulls, but this is only about 80% accurate.

2. sexing of skeletal material can also be attempted by molecular sex determination, utilizing an assay for the amelogenin gene.
