Dental formula of rabbit is

Options

A. `(2033)/(1023)`
B. `(2133)/(1023)`
C. `(2023)/(1023)`
D. `(1303)/(1203)`

Answer

**Step-by-Step Solution:**

1. **Understanding Dental Formula**: The dental formula is a shorthand way of expressing the number and types of teeth in an animal's mouth. It is typically written in a specific format that separates the upper and lower jaws.

2. **Identifying Rabbit's Teeth**: In rabbits, the dental formula consists of incisors, canines, premolars, and molars.

3. **Counting Incisors**:
- Rabbits have 2 upper incisors and 1 lower incisor.
- This can be represented as 2/1 (upper/lower).

4. **Identifying Canines**:
- Rabbits do not have canines.
- Therefore, the count for canines is 0/0.

5. **Counting Premolars**:
- Rabbits have 3 upper premolars and 2 lower premolars.
- This is represented as 3/2 (upper/lower).

6. **Counting Molars**:
- Rabbits have 3 upper molars and 3 lower molars.
- This is represented as 3/3 (upper/lower).

7. **Combining the Counts**:
- Now, we combine all the counts into the dental formula format:
- Upper jaw: Incisors (2), Canines (0), Premolars (3), Molars (3) = 2033
- Lower jaw: Incisors (1), Canines (0), Premolars (2), Molars (3) = 1023

8. **Final Dental Formula**:
- The complete dental formula for a rabbit is thus written as:
- 2033 / 1023

9. **Total Teeth Calculation**:
- Adding them up gives a total of 28 teeth in a rabbit.

**Final Answer**: The dental formula of a rabbit is 2033/1023.
