本专题内容主要包括遗传的物质基础、遗传的基本定律和生物的变异,是历年高考命题的重点。考点主要集中在:(I)以证明DNA是遗传物质的经典实验为素材,考查考生对实验的理解和分析能力;(2)以“中心法则”为核心,考查DNA的复制、转录和翻译等知识;(3)以“遗传特例”为素材创设新情境,考查考生对遗传定律的理解;(4)以生物变异为基础,考查遗传和变异知识在育种上的应用。常以概率计算题、系谱分析题、遗传育种题以及实验分析和设计题的形式出现。
This topic mainly includes the material basis of inheritance, the basic laws of inheritance and biological variation, which are the key points of the college entrance examination proposition over the years. The test centers mainly focus on: (I) Taking the classic experiment of proving that DNA is a genetic material as the material to examine the examinee’s ability to understand and analyze the experiment; (2) Taking “Center Rule” as the core and examining DNA replication, transcription and Translation and other knowledge; (3) “genetic special cases ” as the material to create a new situation, examine the candidates understanding of genetic law; (4) based on biological variation, genetic and mutation testing knowledge of breeding application. Often the probability calculation questions, pedigree analysis questions, genetic breeding questions and experimental analysis and design questions in the form of.
