Heritability of Production Traits
Heritability of production traits is:
- Low
- Medium — Correct Answer
- High
- Zero
Explanation:
Correct Answer: Medium
Production traits (e.g., milk yield, egg production, fat %) have medium heritability.
Heritability Classification by Trait Type
| Trait Category | Heritability (h²) | Examples |
|---|---|---|
| Reproductive traits | Low (0–0.20) | Fertility, litter size, hatchability, calving interval |
| Productive / Economic traits | Medium (0.20–0.40) | Milk yield, egg production, fat % |
| Growth traits | High (>0.40) | Body weight, growth rate, carcass quality |
Key principle: Traits with low h² show high heterosis, and vice versa. Reproductive traits have low h² and high heterosis; growth traits have high h² and low heterosis.
