遗传学作为高中生物的核心主干知识,一直是高考的热点和难点.近几年高考试卷对遗传题中概率计算的形式可谓多样,各具特色.不少学生由于受到能力的限制,不能推出后代概率的变化规律.为了使学生理清典型例题的解题思路,掌握解题方法,准确理解规律变化,正确解答概率计算,笔者特列举如下:一、理清遗传方式,敲定相关个体的基因型,分析发 Genetics, as the core knowledge of high school biology, has always been a hot and difficult issue of college entrance examination. In recent years, the form of probabilistic calculations for high test volumes on genetic subjects can be described as diverse, and each has its own characteristics. Many students cannot introduce future generations because of their limited ability. Probability of the law of change. In order to enable students to clarify the problem of typical examples of problem-solving ideas, master problem-solving methods, accurate understanding of the law changes, correctly answer the probability calculation, the author specifically listed as follows: First, sort out the genetic method, finalize the individual’s genotype , Analysis of hair
