Question:
Expression of more than one phenotypic trait by a single gene is known as:
Expression of more than one phenotypic trait by a single gene is known as:
Show Hint
Pleio- = many; -tropy = change. One gene affects many traits.
Updated On: Jun 10, 2026
- Pleiotropy
- Polygenetic inheritance
- Multiple allelism
- Lyonisation
Show Solution
Verified By Collegedunia
The Correct Option is A
Solution and Explanation
Step 1: Concept
Genetic interactions.
Step 2: Analysis
Pleiotropy occurs when a single gene influences multiple, seemingly unrelated phenotypic traits.
Step 3: Conclusion
The phenomenon described is pleiotropy.
Final Answer: (A)
