生物的性状是由基因控制的,基因位置的判断是高中生物的教学难点,也是高考的常考点。但是,如何判断基因的位置,书中并未涉及,有些资料归纳较为繁琐,不便记忆与应用。经过多年的教学实践,对这一考点教学颇有心得,撰文小结如下,以探讨出解决此类问题的最佳途径。
The traits of organisms are controlled by genes. The determination of gene position is a difficult teaching point for high school biology, and it is also a frequent test point for college entrance examinations. However, how to determine the location of genes is not covered in the book. Some of the information is more complicated and inconvenient for memory and application. After many years of teaching practice, I have learned quite a lot about this test center. The author’s summary is as follows to discuss the best way to solve such problems.
