Blood type, which harbors abundant genetics meaning, is one of the most common phenotypes in human life. With the development of science and technology, its significance is unceasingly updated and new finding is increasingly emerging, which constantly attracts people to decipher the heredity mechanism of blood type. In addition to four main associated contents, i.e., Mendelian inheritance, genetic linkage, gene mutations, and chromosome abnormalities, the blood type case also covers many other aspects of the genetics knowledge. Based on the genetic knowledge context, we can interest the students and improve the teaching output in genetic teaching practice by combining with explaining ABO blood type case and heredity mechanism, expanding leucocyte groups, and introducing infrequent blood type such as Bombay blood, Rh and MN. By carrying out the related experimental teaching, we could drive the student to integrate theory with practice. In genetic experimental teaching, 80% of the students chose this optional experiment, molecular identification of ABO blood type, and it greatly interested them. Using appropriate blood type case in teaching related knowledge, organizing PPT exhi-bition and the debating discussion activities, it could provide opportunities for student to propose their own opinions, guide the student to thinking deeply, and develop their abilities to analyze and solve problem. Afterwards, students will gain in-depth comprehension about the fundamental knowledge of genetics.
Key words： genetics; blood type heredity; case-based teaching; classical case
