Final answer:
The breed in question is known for b) prolific reproduction. Inbreeding in domesticated animals is avoided to prevent health issues and maintain genetic diversity, although selective breeding has been essential for traits like a calm temperament and herding abilities in dogs.
Step-by-step explanation:
The question refers to characteristics of specific animal breeds, which seems to be talking about a breed known for 'prolific reproduction' given the context provided. People who breed domesticated animals generally avoid inbreeding, as this practice can amplify genetic disorders and reduce genetic diversity, leading to health problems such as cancer, hip dysplasia, and heart and kidney issues. Selective breeding can also promote certain desired traits like a calm temperament and the ability to herd, such as in the domestication of dogs. However, too much specialization can be detrimental, as seen in the example of English bulldogs, where many litters need to be delivered by cesarean section because of physical changes resulting from selective breeding.
