Answer
Selective breeding involves choosing parent cats that exhibit certain traits, such as non-allergenic fur or behavior. These selected parents are bred together, producing offspring that inherit these desirable characteristics. Over several generations, breeding within this selected group enhances the frequency of these traits in the population. This method aims to eventually create a lineage of cats that are less likely to provoke allergic reactions in people, making them more suitable as pets for those with allergies.
