遗传部分是每年高考必考的模块,伴性遗传题又是遗传部分常考题型,往往有较高的区分度,因此,“伴性遗传”一节的授课尤为重要。本节教学,以对人类红绿色盲的分析为重点,通过资料分析、问题串引导、学生填表和绘制遗传图解等活动,掌握伴X隐性遗传的特点,再类比推理,学习伴X显性遗传方式,突破教学重难点,达成教学目标,同时,也为进一步学习其它遗传方式打好基础。 Genetic part of the annual exam will be the module, associated genetic problems and genetic part of the often test questions, often have a higher degree of differentiation, therefore, “sex genetics ” section of the lectures is particularly important. In this section, we will focus on the analysis of red-green blindness in human beings. We will grasp the characteristics of X-recessive inheritance with data analysis, guidance of question strings, student filling in forms and drawing of genetic diagrams. Sexual heredity, breaking through teaching difficulties and achieving teaching goals, at the same time, lay the foundation for further study of other hereditary ways.
