摘要
Non遺傳 perturbations, such as environmental change or developmental noise, can induce novel phenotypes. If an induced phenotype appears recurrently and confers a fitness advantage, selection may promote its 遺傳 stabilization. Non遺傳 perturbations can thus initiate 演化ary innovation. 遺傳 variation that is not usually phenotypically visible may play an important role in this process. 族群s under stabilizing selection on a phenotype that is robust to 突變s can accumulate such variation. After non遺傳 perturbations, this variation can produce new phenotypes. We here study the relationship between a phenotype's 突變al robustness and a 族群's potential to generate novel phenotypic variation. To this end, we use a well-studied model of transcriptional regulation circuits that are important in many 演化ary innovat
