Replicate lines, each initially with one hundred pairs of parents selected at 50% intensity, were derived from the Canberra strain. In later generations population size was reduced and selection intensity increased. Three lines were selected without irradiation and five with 1000 r X-rays per generation for thirty generations. Selection was continued until generation 66. Long-term responses were similar in unirradiated and irradiated lines, and there was evidence that genes with large effects influenced response patterns in both groups of lines.
从堪培拉品系中衍生出了复制系，每个系最初有 100 对亲代，选择强度为 50%。在后面的几代中，种群规模减小，选择强度增加。有 3 条系未经辐照选择，5 条系每代用 1000rX 射线选择 30 代。选择一直持续到第 66 代。未辐照和辐照系的长期响应相似，有证据表明，具有较大效应的基因影响了两组系的响应模式。
