Question

analysis of ____ can be used for very precise personal identification. it is even used in anthropology to identify the bones of a deceased person.
fingerprinting
long bone measurement
odontology
dna

Explanation:

DNA analysis is highly specific to an individual. Each person has a unique DNA sequence (except identical twins). Fingerprinting is also unique but less precise in some complex cases compared to DNA. Long - bone measurement and odontology (study of teeth) are more about general characteristics and less precise for individual identification in all scenarios. DNA contains the genetic blueprint of an individual and can be extracted from bones (even old or degraded bones) for identification purposes.

Answer:

DNA
