According to the contents of genetic experimental lessons,the paper sorts out the types of pollution existing in the genetic laboratory and analyzes the possible harm the pollution does to the laboratory technician and the environment.

This paper introduces environmental factors of the pollutants in genetic engineering laboratory in Northwest Agriculture and Forestry University.

Thinking about the creative teaching on genetics experiments;

This article dwells on how to improve teaching quality of genetics experiment and foster students comprehensive qualities by bettering the experiment teaching system,adopting modern teaching techniques and reforming examination mode.

In the researches of genetics experiment teaching, the authors elaborately selected experimental content for training students ability of designing experiments and enlightening their creative thoughts.

Traditional production technique of Drosophila salivary gland chromosome was quite difficulty to manipulate by students in genetic experiment.

Co has been widely used as a radiation resource in general genetic experiments.

By the analysis of the short comings of traditional genetic experimental teaching,this paper put forward the reform of content,method,means as well as the way of assessment in the genetic experimental course,strengthening the construction of laboratory in the teaching activities,expanding the opening level of laboratory,promoting students innovation awa.
