Making full use of mutant mice as research models requires correct characterization of the phenotypes that result from induced or spontaneous genetic mutations.

要充分利用突变小鼠作为研究模式，则需要诱发突变或自发基因突变之正确基因表现型特征。

This, unfortunately, is something we saw several times early on, with a veritable Island of Doctor Moreau full of failed, mutant plastic experiments.
