If a single gene influences several characters it is known as:
If a single gene influences several characters it is known as:
Show Hint
Pleiotropy = one gene → multiple traits.
Updated On: Jun 20, 2026
- Dityropy
- Pleiotropy
- Entropy
- Monotropy
Show Solution
Verified By Collegedunia
The Correct Option is B
Solution and Explanation
Step 1: Understanding gene action.
Genes may affect one or multiple traits depending on their function and expression.
Step 2: Definition of pleiotropy.
Pleiotropy occurs when a single gene controls or influences multiple phenotypic traits.
Step 3: Biological mechanism.
A single gene product may participate in multiple biochemical pathways, leading to multiple effects.
Step 4: Evaluating options.
- Dityropy: Not a genetic term.
- Pleiotropy: Correct concept.
- Entropy: Thermodynamic term.
- Monotropy: Not a standard biological term.
Step 5: Logical reasoning.
Since the question describes multiple effects of a single gene, it matches pleiotropy.
Step 6: Final conclusion.
Therefore, the correct answer is pleiotropy.
Genes may affect one or multiple traits depending on their function and expression.
Step 2: Definition of pleiotropy.
Pleiotropy occurs when a single gene controls or influences multiple phenotypic traits.

- Monotropy: Not a standard biological term.
Step 5: Logical reasoning.
Since the question describes multiple effects of a single gene, it matches pleiotropy.
Step 6: Final conclusion.
Therefore, the correct answer is pleiotropy.
