Ultimate source of organic variation is the process which provide raw materials for evolution is
Or
The concept of sudden genetic change which breeds true in a species is represented as

Options

A. Sexual reproduction
B. Meisosis
C. Mutation
D. Independent assortment

Answer

**Step-by-Step Solution:**

1. **Understanding the Question**: The question asks about the ultimate source of organic variation and the concept of sudden genetic change that breeds true in a species.

2. **Identifying Key Terms**: The key terms here are "organic variation," "raw materials for evolution," "sudden genetic change," and "breeds true in a species."

3. **Analyzing the Options**: The options provided are:
- A) Sexual reproduction
- B) Meiosis
- C) Mutation
- D) Independent assortment

4. **Defining Each Option**:
- **Sexual Reproduction**: This process combines genetic material from two parents, leading to variation but not necessarily sudden changes.
- **Meiosis**: This is the process of cell division that leads to the formation of gametes and contributes to genetic variation through recombination but is not a sudden change.
- **Mutation**: This refers to a sudden change in the DNA sequence of an organism's genome, which can lead to new traits and variations.
- **Independent Assortment**: This is a principle of genetics that describes how different genes independently separate from one another when reproductive cells develop.

5. **Identifying the Correct Answer**: Since the question specifically mentions "sudden genetic change," the most appropriate answer is **C) Mutation**. Mutations are indeed the ultimate source of organic variation, providing the raw materials for evolution.

6. **Conclusion**: Therefore, the answer to the question is **C) Mutation**.
