One of the commonest systems in use in cancer research today is the transplanted tumour in an inbred strain of mice. Reasons are given for suspecting that inbred mice may not be as well-defined genetically as has been supposed. The oft-quoted figure of 20 generations of brother-sister mating appears to be based on the assumption that heterozygosity at only one gene locus is involved in the foundation mating.
当今癌症研究中最常用的系统之一是在近交系小鼠中移植肿瘤。有理由怀疑近交小鼠在基因上可能不像人们所认为的那样明确。经常被引用的20代兄妹交配的数据似乎是基于这样一种假设,即基础交配中仅涉及一个基因座的杂合性。
