Final answer:
Two organisms in the same genus are more likely to have more in common compared to two organisms in the same class.
Step-by-step explanation:
In the Linnaean classification system, organisms are grouped into hierarchical levels, with species being the lowest level and genus being the level above species. Therefore, two organisms that are in the same genus would most likely have more in common compared to two organisms that are in the same class. This is because organisms in the same genus share more recent common ancestry and are more closely related.
