The phrase "bore no resemblance" implies a lack of similarity between two objects or entities. The antonym for this term is "bear resemblance," which means that the two things have some similarity or resemblance. If something bears a resemblance to another, it means that there is a certain level of similarity or familiarity, perhaps in terms of appearance, behavior or character. The opposite of "bore no resemblance" could also be "identical," meaning two things are exactly the same, or "similar," meaning that the objects share some characteristics, while being distinct in other aspects.
