They also tend to be less prone to breed-specific health problems, and there's a school of thought that they're smarter than purebreds. 杂交动物它们的品种有关的健康问题也少,有一个学派也认为它们比纯种动物更加聪明。
Differential Expression of CIDH Gene Between Purebreds and Hybrids in Chicken and Relationship with Heterosis 鸡杂种与纯种间CIDH基因的差异表达及其与杂种优势的关系
The gene frequency at this locus in 4 purebreds of pig was also analyzed. 本研究还分析了多个品种在该座位的等位基因频率。
