What is the purpose of DNA fingerprinting?

  1. Determine an individual's ancestry

  2. Identify genetic disorders

  3. Determine genetic relationships between samples

  4. Find the age of DNA samples

The correct answer is: Determine an individual's ancestry

DNA fingerprinting is a technique used to analyze an individual's unique genetic code. Ancestry is determined by comparing the genetic information from DNA samples to a larger database of genetic information. While options B, C, and D all involve the analysis of DNA, they are not the primary purpose of DNA fingerprinting. Identifying genetic disorders, determining genetic relationships, and finding the age of DNA samples are all possible applications of this technique, but not its main purpose.
