What concept suggests a Zuchon might be healthier than some purebred lines due to its mixed heritage?
Answer
Hybrid vigor
Mixed breeds, often referred to as designer dogs like the Zuchon, are frequently cited as benefiting from a phenomenon known as hybrid vigor. This theoretical advantage suggests that the combination of genes from two distinct purebred lines results in a population that possesses a broader genetic base, potentially leading to a generally hardier and healthier disposition compared to dogs bred strictly within a single, more closed purebred line, thereby mitigating the concentration of specific inherited weaknesses.
