长期生产实践中，人们在驯化动植物使之为人类服务的过程中累积了相当的遗传学知识，对遗传物质与遗传 现象有了初步认识。现代遗传学开始于1900年，百年来，遗传学取得了巨大的进展，人们已经对遗传基因有 了深入了解，正在逐步解析各种遗传现象的分子机制，经典遗传学正在向分子遗传学发展，并逐步演化出分子生物学、基因工程、基因组学等新兴学科。
      作为第一门给学生讲述遗传物质与遗传现象的课程，遗传学的 主要任务是帮助学生了解遗传物质的本质、作用、特征与行为、解析遗传现象本质。它既要在群体水平、进 化水平探讨遗传物质的传递与演化的规律，又要在个体与分子水平探讨遗传物质的本质与发挥作用的分子机 制，是一门贯穿宏观与微观领域的重要基础课程，为学生进一步学习分子生物、基因工程等课程打下扎实的 基础。

During the Long-term production practice，human accumulated considerable genetic knowledge and have an early insights of Genetic material and genetic phenomenon in process of domesticating animals and plants and make them service for us.Modern genetics began in 1900, hundreds of years, it has made tremendous progress,with the in-depth understanding of genetics,the molecular mechanism of each genetics phenomeno are resolving gradually,Classical genetics are to the development of molecular genetics,and gradually evolved into the emerging discipline of molecular biology, genetic engineering and genome.
As the first course that represent Genetic material and genetic phenomenon to students,the primary mission of genetics is to make student understand the nature of the genetic material, role, characteristics and behavior, analytical nature of genetic phenomena.It will investigate the transfer of genetic material with the law of evolution at the population level and the level of evolution,and will Explore the molecular mechanisms of the nature of the genetic material play a role in the level of the individual and Molecular,it is a important and basic corse throughout the areas of macro and micro,it will help student lay foundermental on further study of molecular biology, genetic engineering and other courses.
