Outcrossing has been used as a method for introducing new genetic variability into the high-drinking AA and low-drinking ANA rat lines that had reached their selection limits and were suffering of poor fertility and decreased litter size. The response to the renewed selection for differential alcohol consumption, and the effect of outcrossing upon the components of productivity are reported.
异交已被用作一种方法，将新的遗传变异性引入到高饮酒量的AA大鼠品系和低饮酒量的ANA大鼠品系中，这两个品系已达到其选择极限，并且存在生育力差和窝仔数减少的问题。本文报道了对重新选择差异酒精摄入量的反应，以及异交对生产力组成部分的影响。
