以“孟德尔遗传规律”为基础的遗传概率计算题,在历年高考中都占有重要的地位,而且“常考常新,不断创新”.题型多,难度大,涵盖的能力面广.因此,往往成为许多学生在复习过程中所面临的最大困惑与瓶颈.突破这一难题的有效方法,就是要敢干迎战,善于应战;就是要加大逻辑推理能力的训练,要归纳出解题的思路,总结出解题的方法与技巧.遗传概率计算题的解题思路一般可归纳为:定性→定位→定型→定量.
Genetic probability calculation based on “Mendelian law ” as the basis for the calculation of the genetic probability, all over the years in the college entrance examination occupy an important position, and “often test new, continuous innovation ” .Proble type, difficult, covering ability Therefore, it is often the most confused and bottleneck faced by many students during the review process.An effective way to break this difficult problem is to dare to be dry-fought and good at coping with each other. That is to increase the training of logical reasoning ability Solve the problem of thinking, summed up the methods and techniques to solve the problem.Genetic probability calculation problem solving problems can generally be summarized as: qualitative → positioning → stereotypes → quantitative.
