Final answer:
The claim that responsible breeders are not involved in breed organizations is false. Breeders often join these organizations to ensure best practices and genetic health of the animals. Breed organizations also guide against inbreeding and its associated risks, advocating for genetic diversity and animal welfare.
Step-by-step explanation:
The assertion that responsible breeders are not usually involved in breed organizations is false. Responsible breeders often participate in breed organizations to collaborate on best breeding practices, maintain high standards, and contribute to the health and genetic diversity of the breed. Breed organizations also help in establishing guidelines that discourage inbreiting, which can increase the likelihood of fatal mutations and the expression of deleterious recessive genes leading to abnormalities and disease susceptibility. Such organizations aim to preserve genetic diversity, maintaining the overall health of the breed.
Breeders try to avoid inbreeding because it can have negative consequences on the health and genetic vigor of the animals. The practice of selective breeding can sometimes be detrimental when not properly managed, as seen in cases like the English bulldog, where severe health problems have arisen due to extreme breed characteristics. This serves as a reminder of the importance of genetic diversity and the dangers of narrowing the gene pool through selective breeding.
