Independent genes that copy other genes so as to produce a similar effect are called

Options

A. lethal genes
B. Duplicate genes
C. Complementary genes
D. None of the above

Answer

To solve the question regarding independent genes that copy other genes to produce a similar effect, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding the Question**: The question asks for a specific type of gene that can independently copy other genes and produce a similar effect.

2. **Identifying the Options**: The options given are:
- Lethal genes
- Duplicate genes
- Complementary genes
- None of the above

3. **Analyzing Each Option**:
- **Lethal Genes**: These are genes that can cause the death of an organism when present in certain combinations. They do not fit the description of copying other genes to produce a similar effect.
- **Complementary Genes**: These genes work together to produce a specific phenotype, but they do not necessarily copy other genes. They complement each other rather than duplicating effects.
- **Duplicate Genes**: These genes are independent and can produce similar effects as other genes they mimic. This fits the description provided in the question.
- **None of the Above**: This option would imply that none of the previous options are correct, which is not the case here.

4. **Conclusion**: Based on the analysis, the correct answer is **Duplicate genes**. These are the independent genes that can copy other genes and produce a similar effect.

### Final Answer:
**Duplicate genes**
