A linebreeding may produce a puppy with magnificent qualities, but if those qualities are not present in any of the ancestors the pup has been linebred on, it may not breed true.

血系繁殖以生出品质超群的小~~如果这些品质并没有在血系繁殖的小任何祖先身上呈~~就不准确的繁殖。

This has led some breed clubs to discourage the use of linebreeding or inbreeding in an attempt to maintain gene pool diversity.

因此，这足以证明受欢迎的公犬对其品种的延续有着潜移默化的影响。
