NEET Biology: Biology - Principles of Inheritance and Variation questions with solutions

Q1. Which of the following patterns of reproduction is the major cause of variation?

1. Sexual reproduction
2. Asexual reproduction
3. Both of these
4. None of these

Answer: Sexual reproduction

Sexual reproduction is the major cause of variation because it combines genetic material from two parents, creating new gene combinations in offspring. Asexual reproduction usually produces genetically identical offspring, so it contributes much less variation.
