Abstract
Quantitative geneticists traditionally attribute phenotypic variation to genetic or environmental sources. New findings with near-clonal mice raised in a single enriched environment demonstrated significant developmental and behavioural divergence. This suggests intriguing possibilities for how (epi)genomes and environments might interact to drive phenotypic individuality, thus shaping evolutionary pathways.
摘要
传统上，数量遗传学家将表型变异归因于遗传或环境来源。在单一丰富环境中饲养的近克隆小鼠的新发现表明，它们在发育和行为上存在显著差异。这为（表观）基因组和环境如何相互作用以驱动表型个体性从而塑造进化途径提供了有趣的可能性。
