The correct Answer is:
To solve the question regarding the correctness of the two statements provided, we will analyze each statement step by step. ### Step 1: Analyze Statement A **Statement A:** "Variation at genetic level arises due to mutations." - **Explanation:** Mutations are changes in the DNA sequence of an organism's genome. These changes can lead to variations in traits among individuals. Therefore, it is accurate to say that genetic variation can arise from mutations. **Conclusion for Statement A:** This statement is **correct**. ### Step 2: Analyze Statement B **Statement B:** "Technique of DNA fingerprinting was initially developed by Alec Jeffreys." - **Explanation:** Alec Jeffreys is indeed credited with the development of DNA fingerprinting in the 1980s. This technique allows for the identification of individuals based on their unique DNA profiles. **Conclusion for Statement B:** This statement is also **correct**. ### Final Conclusion Both statements A and B are correct. Therefore, the correct answer to the question is that both statements are true. ### Summary of the Solution: - Statement A is correct because mutations lead to genetic variation. - Statement B is correct as Alec Jeffreys developed the DNA fingerprinting technique. - Thus, both statements A and B are correct.
