DNA fingerprinting method is very useful for

Options

A. DNA tests for identity & relation ship
B. Forensic studies
C. Polymorphism
D. All of the above

Answer

**Step-by-Step Solution:**

1. **Understanding DNA Fingerprinting**: DNA fingerprinting is a technique used to identify individuals based on their unique DNA patterns. It was developed by Dr. Alec Jeffreys in 1984 and has since become a crucial tool in various fields.

2. **Applications of DNA Fingerprinting**:
- **DNA Test for Identity and Relationships**: DNA fingerprinting can determine familial relationships, such as paternity tests, by comparing the DNA profiles of individuals.
- **Forensic Studies**: In forensic science, DNA fingerprinting is used to identify suspects in criminal cases by matching DNA found at crime scenes with that of potential suspects.
- **Polymorphism**: DNA fingerprinting exploits the variations in DNA sequences among individuals, known as polymorphisms, which are key to distinguishing one person's DNA from another's.

3. **Conclusion**: Given the various applications of DNA fingerprinting, it is evident that it serves multiple purposes, including identity verification, forensic analysis, and studying genetic variations. Therefore, the correct answer to the question is "all of the above."

**Final Answer**: All of the above.
