Dental Formula of Mare
Dental formula of female horse (mare) is:
- 2(I 0/4, C 0/0, PM 3/3, M 3/3)
- 2(I 3/3, C 0/0, PM 3/3, M 3/3) — Correct Answer
- 2(I 3/3, C 1/1, PM 3/3, M 3/3)
- 2(I 3/3, C 1/1, PM 4/4, M 3/3)
Explanation:
Correct Answer: 2(I 3/3, C 0/0, PM 3/3, M 3/3)
The dental formula of the mare (female horse) is 2(I 3/3, C 0/0, PM 3/3, M 3/3) = 36 teeth (Table 33). The key distinction from the stallion is that canines are absent in the mare.
Comparison
- Stallion: 2(I 3/3, C 1/1, PM 3/3, M 3/3) = 40 teeth (has canines)
- Mare: 2(I 3/3, C 0/0, PM 3/3, M 3/3) = 36 teeth (no canines)
Why Other Options Are Wrong
- Option A — 2(I 0/4, C 0/0, PM 3/3, M 3/3): This is the dental formula of ruminants (cow, buffalo, sheep, goat) = 32 teeth.
- Option C — 2(I 3/3, C 1/1, PM 3/3, M 3/3): This is the stallion's formula (40 teeth) — canines present.
- Option D — 2(I 3/3, C 1/1, PM 4/4, M 3/3): This is the pig's dental formula = 44 teeth.
