The correct Answer is:
**Step-by-Step Solution:** 1. **Understanding Holandric Genes**: Holandric genes are defined as genes that are located on the Y chromosome. These genes are unique because they are passed directly from father to son. 2. **Identifying the Chromosomes**: In the context of inheritance, we have three types of chromosomes to consider: autosomes, X chromosomes, and Y chromosomes. - Autosomes are non-sex chromosomes and do not play a role in sex-linked inheritance. - X chromosomes are one of the sex chromosomes but are not directly transmitted from father to son. - Y chromosomes are the male sex chromosomes that are inherited from father to son. 3. **Direct Transmission of Traits**: The question asks about the direct transmission of traits from father to son. Since holandric genes are located on the Y chromosome, they are inherited directly from the father to his male offspring. 4. **Conclusion**: Therefore, the correct answer to the question is that holandric genes, or the direct transmission of traits from father to son, occurs through the Y chromosome. **Final Answer**: The correct option is Y chromosome. ---
