Genes located on differential region of Y-chromosome are called

Options

A. XY linked genes
B. Holandric genes
C. Autosomal genes
D. Mutant genes

Answer

**Step-by-Step Solution:**

1. **Understanding the Question**: The question asks about the genes located on the differential region of the Y chromosome. We need to identify the specific term used to describe these genes.

2. **Identifying the Options**: The options given are:
- XY linked genes
- Holandric genes
- Autosomal genes
- Mutant genes

3. **Analyzing Each Option**:
- **XY linked genes**: This term suggests genes that are linked to both X and Y chromosomes, which is not specific to the differential region of the Y chromosome.
- **Holandric genes**: These are genes that are located on the differential region of the Y chromosome and are typically expressed only in males.
- **Autosomal genes**: These are genes located on non-sex chromosomes (autosomes) and do not pertain to the Y chromosome.
- **Mutant genes**: This term refers to genes that have undergone mutations and does not specifically relate to the Y chromosome.

4. **Correct Option**: Based on the analysis, the correct answer is **Holandric genes**. These genes are confined to the differential region of the Y chromosome and are typically expressed in males.

5. **Conclusion**: Therefore, the genes located on the differential region of the Y chromosome are called **Holandric genes**.
