Heritability Level of Production Traits
Heritability of production traits is:
- Low
- Medium — Correct Answer
- High
- Zero
Explanation:
Correct Answer: Medium
Heritability of production traits is Medium.
Heritability by Trait Category
| Trait Category | Heritability | Examples |
|---|---|---|
| Reproductive traits | Low (h² < 0.20) | Fertility, litter size, calving interval, hatchability |
| Productive traits | Medium (h² = 0.20–0.40) | Milk yield, egg production, fat % |
| Growth traits | High (h² > 0.40) | Body weight, growth rate, feed efficiency, carcass quality |
Note: Traits with low heritability show high heterosis, and vice versa. Individual selection and pedigree selection are effective for high h² traits, while progeny testing and family selection work better for low h² traits.
