Select the incorrect statement w.r.t asexual reproduction

Options

A. It can occur with or without gamete fusion
B. It can occur through unspecialised or speciallised parts of the parent.
C. Simple and quick method of reproduction
D. Common mode of reproduction in lower organisms

Answer

To solve the question "Select the incorrect statement with respect to asexual reproduction," we will analyze each statement provided in the options.

### Step-by-Step Solution:

1. **Understand Asexual Reproduction**: Asexual reproduction is a mode of reproduction that involves only one parent. It does not involve the formation or fusion of gametes, which are the reproductive cells (sperm and egg).

2. **Evaluate the Statements**:
- **Statement A**: "It can occur with or without gamete fusion."
- This statement is **incorrect** because asexual reproduction does not involve gametes at all. Gamete fusion is a characteristic of sexual reproduction, not asexual reproduction.

- **Statement B**: "It can occur through unspecialized or specialized parts of the parent."
- This statement is **correct**. Asexual reproduction can occur through various means, including simple division (like in amoeba) or through specialized structures (like runners in plants).

- **Statement C**: "It is a simple and quick method of reproduction."
- This statement is **correct**. Asexual reproduction is generally faster and simpler because it does not require the processes of gamete formation and fusion.

- **Statement D**: "It is a common mode of reproduction in lower organisms."
- This statement is **correct**. Many lower organisms, such as bacteria, fungi, and some protists, reproduce asexually.

3. **Identify the Incorrect Statement**: After evaluating all the statements, we find that Statement A is the only incorrect statement regarding asexual reproduction.

### Final Answer:
The incorrect statement with respect to asexual reproduction is **Statement A**: "It can occur with or without gamete fusion."
