DNA finger printing is useful for study of :

Options

A. Forensics
B. Polymorphism
C. identity and relations
D. all of therse

Answer

**Step-by-Step Solution:**

1. **Understanding DNA Fingerprinting**: DNA fingerprinting is a technique used to identify individuals based on their unique DNA profiles. It focuses on variations in DNA sequences that can distinguish one person from another.

2. **Identifying Applications**: The applications of DNA fingerprinting include:
- **Forensic Science**: It is used to solve crimes by matching DNA samples from crime scenes with suspects.
- **Paternity Testing**: This technique helps in determining biological relationships, such as confirming a father-child relationship.
- **Identity Verification**: It can be used to confirm the identity of individuals in various situations, such as immigration or legal cases.

3. **Understanding Polymorphism**: DNA fingerprinting relies on polymorphisms, which are variations in the DNA sequence. These variations are often found in repetitive DNA sequences that are unique to each individual.

4. **Conclusion**: Since DNA fingerprinting is useful for forensic applications, establishing identity, and determining relationships, the correct answer to the question is that it is useful for the study of "forensic polymorphism, identity, and relations," which encompasses all of these applications.

5. **Final Answer**: Therefore, the correct option is "all of these."
