A Savannah cat is a cross breed between the domestic cat and a medium-sized wild African cat called the Serval.

萨凡纳猫是由家猫和一种被称为薮猫的中等体型的非洲野生猫杂交的品种。

A Canadian study found GM-fish could potentially cross breed but the company which created the salmon said any risks were negligible.

加拿大研究发现转基因鱼或可以实现基因杂交改造，培育该三文鱼的企业表示其风险完全可以忽略不计。

The improvement is by no means generally due to crossing different breeds; all the best breeders are strongly opposed to this practice, except sometimes among closely allied sub-breeds.

这种改进绝非一般归因于杂交不同品种。所有最好的育种者都强烈反对这种做法， 除了有时在密切相关的亚品种中。
