Based on prior knowledge, it is difficult to determine specific typical values for the feature "Pregnancies" that directly relate to the target variable "Does this person have diabetes?". However, since the feature represents the number of times a person has been pregnant, it is reasonable to assume that both the 'yes' and 'no' classes can have a range of values for this feature. Therefore, a general representation with typical values for both classes is provided in the dictionary above.
