Select the odd one w.r.t sexual reproduction

Options

A. Diverse organisms show great diversity in sexual mode of reproduction
B. Juvenile phase is called vegetative phase in plants
C. Offsprings are not identical to the parents
D. Fusion of gametes results in formation of zygote

Answer

To solve the question "Select the odd one with respect to sexual reproduction," we need to analyze the given options and determine which one does not align with the principles of sexual reproduction.

### Step-by-Step Solution:

1. **Understanding Sexual Reproduction**:
- Sexual reproduction involves the fusion of gametes (sperm and egg) to form a zygote. This process typically results in offspring that are genetically diverse from the parents.

2. **Analyzing the Options**:
- **Option 1**: "Diverse organisms show great diversity in sexual mode of reproduction."
- This statement is true as sexual reproduction can vary widely among different organisms.

- **Option 2**: "Juvenile phase is called vegetative phasing in plants."
- This statement is also true. In plants, the juvenile phase can be referred to as the vegetative phase, where the plant grows and prepares for sexual reproduction.

- **Option 3**: "Offsprings are not identical to the parents."
- This statement is correct. Due to genetic recombination and crossing over during meiosis, offspring produced through sexual reproduction are genetically different from their parents.

- **Option 4**: "Fusion of gametes results in the formation of zygote."
- This statement is true and is a fundamental aspect of sexual reproduction.

3. **Identifying the Odd One Out**:
- Upon reviewing the options, **Option 2** ("Juvenile phase is called vegetative phasing in plants") stands out as the odd one because it refers to a phase in plant development rather than directly addressing sexual reproduction. The other options are directly related to the process and outcomes of sexual reproduction.

4. **Conclusion**:
- Therefore, the odd one with respect to sexual reproduction is **Option 2**.
