 # Analysis of skull shape and size, supraorbital ridge, extension of zygomatic arch beyond external meatus, measurement of angle of mandible helps in:

A. Sex determination

B. Racial determination

C. Age determination

D. Ethnicity determination

The correct answer is A. Sex determination.

Skull and facial features like mastoid process, supraorbital ridges, size and architecture of skull can help in determining the sex of patient in 94% cases. 

Sex differentiation (Sexing) of a specimen: It can be done using methods as below: 

 Using craniofacial morphology: The following 6 traits give accurate results 94% times: 

- Mastoid process 

- Supraorbital ridge \

- Size and architecture of skull 

- Extension of the zygomatic arch beyond the external auditory canal 

- Nasal aperture and 

- Gonial angle (on the mandible) (Including more features increases accuracy by 2%)
