遗传学相关技术已越来越深入影响着人类的健康与生活。从理论到实践，以学科应用的典型案例开展教学，是近年来遗传学教学领域较为热衷的新模式。本文以生活中“喝酒脸红”表型为例，将表型分析、群体分析和家系分析等多角度、多层面的遗传学理论知识与实践案例有机融合，在激发学生主动学习兴趣的同时，系统培养学生理论联系实际，从实践中发现问题、解决问题的能力，并在实践中进一步拓展学习基因检测相关的生命伦理、基因信息保护、遗传资源保护等知识，激发学生主动思考，以期达到全面培养学生的科学思维能力与科学素养的目的。

Genetic related technologies are increasingly influencing human health and life. From theory to practice, teaching through typical cases of disciplinary applications has become a popular new model in the field of genetics education. This experiment takes the phenotype case of “alcohol flush” as an example, organically integrating genetic knowledge from multiple perspectives and levels such as phenotypic analysis, population genetic analysis and pedigree analysis with experimental cases. In teaching practice, the “alcohol flush” case study can greatly stimulate students’ interest in active learning, cultivate students’ ability to connect theory with practice, discover and solve problems from practice, and further expand their learning of genetic testing related bioethics, genetic information protection, genetic resource protection, and other knowledge through personal practical teaching, thus cultivate students’ scientific thinking ability and scientific literacy.
