alleryThe existence of two successive sets of teeth, the milk teeth and permanent teeth, in a rabbit is called:
ADiphyodont dentition
BHeterodont dentition
CThecodont dentition
DMonophyodont dentition
Answer & Solution
Correct answer: A. Diphyodont dentition
1. The rabbit grows two successive sets of teeth in its life.
2. The first set is the milk teeth and the second the permanent teeth.
3. Having two such sets is called diphyodont dentition.
4. So diphyodont dentition is correct.
5. Option B heterodont refers to having different kinds of teeth, the trap.
6. Option D monophyodont means a single set, the opposite, so it is wrong.
7. Option C thecodont describes teeth set in sockets, a different feature.
