Question:
Height of a human being is a typical example of which mode of inheritance?
Height of a human being is a typical example of which mode of inheritance?
Show Hint
Polygenic = Many genes, continuous variation (Bell curve). Multi-allelic = Many versions of ONE gene (Blood types).

- Pleiotropic Inheritance
- Cytoplasmic Inheritance
- Multi-allelic Inheritance
- Polygenic Inheritance
Show Solution
Verified By Collegedunia
The Correct Option is D
Solution and Explanation
Step 1: Concept
Different traits follow different inheritance patterns, ranging from single-gene traits to those controlled by many genes.
Step 2: Analysis of Human Height
Human height does not fall into discrete categories (like "tall" vs "short") but shows a continuous range of variation.
Step 3: Reasoning
Traits that show continuous variation and are controlled by the additive effect of multiple genes are called polygenic traits.
Step 4: Conclusion
Human height is a classic example of polygenic inheritance. Final Answer: (D)
