Polygenic Inheritance is a phenomenon in which traits are controlled by:

Options

A. One gene
B. Two genes
C. Three or more genes
D. Three of less genes

Explanation

**Step-by-Step Text Solution:**

1. **Understanding Polygenic Inheritance**: Polygenic inheritance refers to the phenomenon where multiple genes (more than one) contribute to a single trait. This means that rather than a single gene controlling a trait, several genes work together to influence the outcome.

2. **Identifying the Options**: The question provides several options regarding how many genes control traits in polygenic inheritance:
- 1 gene
- 2 genes
- 3 or more genes
- 3 or less genes

3. **Analyzing the Term 'Poly'**: The prefix 'poly' in polygenic indicates 'many' or 'multiple'. This suggests that polygenic inheritance involves more than one gene.

4. **Determining the Correct Answer**: Since polygenic inheritance involves multiple genes, the correct option must reflect that. The option "3 or more genes" aligns with the definition of polygenic inheritance, as it indicates that at least three genes are involved in controlling the trait.

5. **Conclusion**: Therefore, the correct answer to the question is that traits in polygenic inheritance are controlled by "3 or more genes".
