A "breed" refers to a specific group of domesticated animals or plants that share distinct characteristics and traits. Breeds are often developed through selective breeding, where individuals with desirable qualities are chosen to reproduce. This process can enhance certain features, such as size, color, or behavior, making each breed unique. In animals, common examples include dogs, cats, and horses, each having various breeds like Labrador Retrievers or Persian cats. In plants, breeds can refer to cultivated varieties of crops, such as wheat or roses, which are bred for specific traits like yield or flower color.
