分离规律的教学目的,主要是使学生了解等位基因的遗传行为与相对性状遗传表现之间的因果联系,从而理解性状分离的遗传原理。在精讲多练的课堂教学中,教师的精讲要抓住关键性概念和原理,以及与概念和原理有关的感性材料;学生课堂上的练习题要形式多样化,练在基础知识上,做到少而精。分析感性材料要突出本质分离规律和自由组合规律的提出都经历了由现象到假说、到理论的过程。学生理解概念和原理,也要求有相应的感性知识为基础,采取
The purpose of the teaching of separation is mainly to enable students to understand the causal relationship between the genetic behavior of alleles and the genetic performance of the relative trait so as to understand the genetic principle of trait separation. In lecturing and practicing in classroom teaching, the teachers ’lectures should grasp the key concepts and principles as well as the sensible materials related to the concepts and principles. The exercises in the students’ classroom should be diversified in form, practiced in the basic knowledge, Be less and less Analysis of the perceptual material to highlight the nature of the law of separation and the freedom to combine the law have experienced the phenomenon from the hypothesis to the theoretical process. Students understand the concepts and principles, but also require a corresponding basis of perceptual knowledge to take
