Which of the following is a true for sexual reproduction?

Options

A. It provides opportunities for variations
B. It maintain uniform genetic purity of organisms for successive generations
C. It preserves genetic information for several generations
D. It permits multiplication of desired genes only

Answer

To determine which statement is true about sexual reproduction, let's analyze each option step by step.

### Step-by-Step Solution:

1. **Understanding Sexual Reproduction**:
- Sexual reproduction involves the combination of genetic material from two parents, leading to offspring that have genetic variation.

2. **Evaluating the Options**:
- **Option 1**: "It provides opportunities for variation."
- This statement is true. Sexual reproduction introduces genetic diversity through the mixing of genes from two parents, resulting in varied offspring.

- **Option 2**: "It maintains uniform genetic purity of organisms for the successive generation."
- This statement is false. Sexual reproduction does not maintain genetic purity; instead, it creates diverse offspring, leading to variations in genetic traits.

- **Option 3**: "It preserves genetic information for several generations."
- This statement is also false. While some genetic information may be preserved, sexual reproduction tends to introduce changes and variations in genetic information across generations.

- **Option 4**: "It permits the multiplication of desired genes only."
- This statement is incorrect. Sexual reproduction does not selectively multiply only desired genes; it can also propagate undesired traits due to the mixing of genetic material.

3. **Conclusion**:
- After evaluating all the options, the only true statement regarding sexual reproduction is **Option 1**: "It provides opportunities for variation."

### Final Answer:
The correct answer is: **It provides opportunities for variation.**
