颜色模式是一种迷人的生物特征，在几个基本的生态和进化过程中发挥着关键作用。它们对表型分化的过程提供了重要的见解。颜色模式也提供了引人注目的趋同的例子，表型相似性的独立进化。在基因组测序和编辑的时代，现在越来越有可能从分子角度研究分歧和趋同。最近的工作在慈鲷鱼建议独立的遗传变化在同一基因组位点的原因平行的损失和收益的条纹颜色模式。与其他动物群体的证据一起，出现了一幅图片，即基因组热点的独立突变与遗传和生理上不同的颜色模式表型（如条纹图案和反阴影）的发散和收敛进化有关。
Color patterns are a fascinating organismal feature and play key roles in several fundamental ecological and evolutionary processes. They give important insights into the process of phenotypic divergence. Color patterns also provide striking examples of convergence, the independent evolution of phenotypic similarities. In the era of genome sequencing and editing it is now increasingly possible to study divergence and convergence from a molecular perspective. Recent work in cichlid fishes suggests independent genetic changes at the same genomic locus as the cause for the parallel losses and gains of stripe color patterns. Together with evidence from other animal groups, a picture emerges whereby independent mutations at genomic hotspots associate with both the divergent and convergent evolution of genetically and physiologically distinct color pattern phenotypes such as stripe patterns and countershading.
