Linebreeding

定义 Definition

系谱繁育 / 系统近交(线繁育):一种有计划的繁殖方式,通过在族谱中重复使用某个优秀祖先的血缘来固定理想性状;通常比“紧密近交”更温和,但仍会提高近亲交配的比例与遗传风险。(该词也常见于犬、马、牛等育种语境。)

例句 Examples

Linebreeding can help preserve desired traits in a working dog line.
系谱繁育可以帮助在工作犬家系中保留理想性状。

Because linebreeding increases genetic relatedness, responsible breeders monitor health outcomes and avoid pairing animals that would raise the inbreeding coefficient too high.
由于系谱繁育会提高亲缘相关性,负责任的育种者会监测健康结果,并避免让近交系数升得过高的配对。
