Abstract:

We explored the practical effect of the genetic analysis of simple sequence length polymorphism (SSLP) molecular markers in rice in the genetics lab course. Two parents and their F2 population were analyzed and detected with three SSLP molecular markers that located on two chromosomes of the rice genome. The markers’ genotype data were used to verify the three laws of genetics, including segregation, independent assortment and linkage and crossing-over. Our practice has proved not only beneficial to deepen students’ understandings about the three laws of genetics, but also conducive to cultivate students’ interests in research and innovation and improve their skills and comprehensive analysis abilities. At the same time, the application scope of the experiment was discussed. This comprehensive experiment is also useful for the transformation of scientific research achievements into undergraduate experimental teaching.

Key words: genetics lab course, the three laws of genetics, molecular markers, converting the research to the teaching
