摘要: 小鼠是最常用的哺乳动物模式生物,其毛色有白色、灰色、黄色、黑色等,是典型的孟德尔遗传性状。但在本科遗传学教学中,一般只在介绍隐性致死基因的时候才提到小鼠毛色遗传的例子。作者深入挖掘和整理了小鼠毛色遗传的分子机制,并把这个例子贯穿于讲解孟德尔遗传以及介绍分子遗传学的基因结构、基因功能、基因调控、基因互作、基因的表观遗传学修饰和数量性状遗传等,尝试用同一个案例贯穿本科遗传学教学,培养学生建立由表及里的系统分析能力,既凸显遗传学研究的前沿性和完整性,又吸引了学生的注意力,激发了学生的学习兴趣,收到了很好的教学效果。

Abstract: Mice are the most commonly used mammalian model. The coat colors of mice are typical Mendelian traits, which have various colors such as white, black, yellow and agouti. The inheritance of mouse coat color is usually stated as an example only in teaching the knowledge of recessive lethal alleles. After searched the related literatures and summarized the molecular mechanisms of mouse coat color inheritance, we further expanded the application of this example into the introduction of the basic concepts of alleles and Mendelian laws, demonstration of the gene structure and function, regulation of gene expression, gene interaction, epigenetic modification, quantitative genetics, as well as evolutionary genetics. By running this example through the whole genetics-teaching lectures, we help the student to form a systemic and developmental view of genetic analysis. At the same time, this teaching approach not only highlights the advancement and integrity of genetics, but also results in a good teaching effect on inspiring the students’ interest and attracting students’ attention.
