Differentiating Buffalo Subspecies
Main difference between water buffalo & swamp buffalo is in-
- Coat colour
- Horn colour
- Chromosome number — Correct Answer
- Hump
Explanation:
Correct Answer: Chromosome Number
The primary distinguishing biological feature between River/Water buffalo and Swamp buffalo is their chromosome number (2N). River buffalo has 2N = 50 while Swamp buffalo has 2N = 48.
Buffalo Chromosome Comparison
| Feature | River/Water Buffalo | Swamp Buffalo |
|---|---|---|
| Chromosome (2N) | 50 | 48 |
| Scientific name | Bubalus bubalis | Bubalus bubalis carabanesis |
| Primary use | Milk & meat | Draught (field work) |
| Habitat | India, Pakistan, Egypt | South East Asia |
| Body build | Heavier, more milk | Sturdier, more work capacity |
Key Chromosome Numbers for Revision
- River/Water Buffalo: 50
- Swamp Buffalo: 48
- Cattle (zebu/exotic), Goat, Yak: 60
- Sheep: 54
- Horse: 64
Why Other Options Are Wrong
- Coat colour → both are predominantly black/grey; not a defining taxonomic difference
- Horn colour → not the main distinguishing biological criterion
- Hump → buffaloes do not have humps (cattle do); irrelevant here
