"Big four" components of biological profile are :

  • A.Race, sex, height, age
  • B.Race, sex, height, skeleton
  • C.Race, sex, stature, blood groups
  • D.Teeth, height, race, sex

Answer: A

The big four are race, sex, height and age.

In forensic anthropology the biological profile of unidentified remains rests on four basic determinations: ancestry (race), sex, stature (height) and age at death. Together they narrow the list of missing persons who could match the remains, before individual features such as old fractures, dental work or DNA are used to confirm identity.

A skeleton is the material examined, not a component of the profile. Blood groups cannot usually be found from skeletal remains and are not one of the four, and teeth are a source of evidence for age, not a component in their own right.
