Pleiotropic genes have

Options

A. repressed phenotype
B. hidden phenotype
C. multiple phenotype
D. all of these

Answer

**Step-by-Step Solution:**

1. **Understanding Pleiotropy**: Pleiotropic genes are those that can influence multiple phenotypic traits. This means that a single gene can have effects on more than one characteristic or trait in an organism.

2. **Analyzing the Options**:
- **Option A: Suppressed phenotype** - This implies that the gene suppresses traits, which is not a defining characteristic of pleiotropy.
- **Option B: Hidden phenotype** - This suggests that the traits are not expressed, which also does not align with the concept of pleiotropy.
- **Option C: Multiple phenotype** - This accurately reflects the definition of pleiotropy, as it indicates that one gene can affect multiple traits.
- **Option D: All of these** - Since options A and B do not correctly describe pleiotropy, this option cannot be correct.

3. **Conclusion**: The correct answer is **Option C: multiple phenotype**, as pleiotropic genes are known for their ability to affect more than one phenotypic trait.

**Final Answer**: C) multiple phenotype
