dubious_for_taxon 可疑_于_分类 可疑_于_分类 true true RO:0002174 S dubious_for_taxon T if it is probably the case that no instances of S can be found in any instance of T. dubious_for_taxon dubious_for_taxon this relation lacks a strong logical interpretation, but can be used in place of never_in_taxon where it is desirable to state that the definition of the class is too strict for the taxon under consideration, but placing a never_in_taxon link would result in a chain of inconsistencies that will take time to resolve. Example: metencephalon in teleost uberon S可疑_于_分类 T如果在T的任何实例中可能找不到S的实例， 可疑_于_分类 可疑_于_分类 这种关系缺乏一个强有力的逻辑解释，但可以以理想状态用在不_在_分类中，其中有必要说明该类的定义对于所考虑的分类群来说过于严格，但放置一个不_在_分类链接会导致链的不一致，需要时间来解决。例如：后脑硬骨
