linebreeding

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

因此，这足以证明受欢迎公犬对其品种延续有着潜移默化影。

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.

内繁殖可以生出品质超群小狗~~但是如果这些品质并有内繁殖小狗任何祖先身上呈现~~可能就是不准确繁殖。
