ANATOMY

Detailed explanation-1: -However, the pelvis is the best sex-related skeletal indicator, because of distinct features adapted for childbearing. The skull also has features that can indicate sex, though slightly less reliably.

Detailed explanation-2: -The angle formed by the ischio-pubic ramus below the pubic symphysis is wider and more ‘U-shaped’ in females than in males. Males have a narrower subpubic angle that tends to be more ‘V-shaped’.

Detailed explanation-3: -Among seven features observed on the pelvic bones, the least reliable single sex indicator was the width of the great sciatic notch (with accuracy of 79.15%). Looking at the skull alone, sex was correctly determined in 70.56% cases.

Detailed explanation-4: -Pelvic skeleton includes two hip bones, sacrum and coccyx. The geometry of bony pelvis differs significantly between males and females – the phenomena caused by adaptation to the obstetric demands.
