Animals Lacking Canine Teeth
Canine teeth are absent in:
- Cattle
- Mare
- Stallion
- Both a & b — Correct Answer
Explanation:
Correct Answer: Both a & b
Canine teeth are absent in both Cattle (all ruminants) and Mare (female horse).
- Cattle: All ruminants lack canine teeth — dental formula 2(I 0/4, C 0/0, PM 3/3, M 3/3) = 32 teeth.
- Mare: Female horse lacks canines — dental formula 2(I 3/3, C 0/0, PM 3/3, M 3/3) = 36 teeth.
Key Distinction
The stallion (male horse) DOES have canine teeth: 2(I 3/3, C 1/1, PM 3/3, M 3/3) = 40 teeth. This 4-tooth difference (40 - 36 = 4 canines) is the sex-based dental distinction in horses.
Why Other Options Are Wrong
- Cattle alone: Correct but incomplete — mare also lacks canines.
- Mare alone: Correct but incomplete — cattle also lacks canines.
- Stallion: Stallion HAS canine teeth (1 per quadrant = 4 total).
