To determine the predominant type of tooth trait in a population, you'd generally look for the most common phenotype. In humans, for example, the predominant dental trait is the presence of wisdom teeth. However, for specific populations or in the context of certain studies or discussions about dental traits, the common traits may vary.
Typically, in a broad human population, traits such as the presence of a certain number of teeth (32 is the standard for adults) or the presence of specific types of teeth (incisors, canines, premolars, molars) can be considered.
If you're referring to a specific study or population regarding dental traits, please provide more context or details to give a more accurate answer.
