Genes located on X- chromopsomes are known as

Options

A. Epistatic genes
B. Holandric genes
C. Operator genes
D. Antiepistatic genes

Answer

To solve the question regarding the genes located on X-chromosomes, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Question**: We need to identify the correct term for genes that are located on the X-chromosome.

2. **Analyze the Options**:
- **Epistatic Genes**: These genes determine whether a trait will be expressed or not, but they are not specific to the X-chromosome.
- **Holandric Genes**: These are genes found on the Y-chromosome, not the X-chromosome.
- **Operator Genes**: These genes are involved in the transcription process and are not specific to any chromosome.
- **Anti-epistatic Genes**: These are also known as non-epistatic genes and function oppositely to epistatic genes. They are located on the X-chromosome.

3. **Identify the Correct Answer**: Based on the analysis, the correct answer is **anti-epistatic genes**, as they are located on the X-chromosome.

4. **Final Answer**: Genes located on X-chromosomes are known as **anti-epistatic genes**.
