摘  要:
动物毛色是研究其表型遗传和进化机制的模型之一。相比于其野生祖先,家养动物被毛表型具有更丰富的多样性,这种表型差异主要由遗传、进化和选择引起。综述了动物的驯化历史、人工选择和潜在的遗传因素对动物毛色变异的影响,为阐明家养动物毛色变异类型与其野生祖先多样性差异存在的潜在原因以及动物毛色形成的遗传进化机制提供参考。

摘  要:
Animal coat color is a powerful model for studying the genetic mechanisms that determine phenotype.Most domestic animals,in contrast to their wild ancestors,are often characterized by a huge variability of coat color phenotypes.This variability results from genetics,evolution and artificial selection.In this review,we focus on the animals domesticating history,artificial selection and underlying genetic causes that have resulted in the observed increase of color variation in domestic animals compared to their wild ancestors,so as to understand the genetic and evolutionary mechanisms of animal coloration.
