对现代生物进化理论的考查,从近三年全国各地高考卷来看,题量逐渐增加,题型也由单一选择题转化为选择题和简答题。为便于学生系统了解现代生物进化理论的主要内容,熟悉与此有关的计算,在此对现代生物进化理论的主要内容及涉及的和基因频率有关的计算归纳如下。一、现代进化理论的主要内容种群是生物进化的基本单位;突变和基因重组产生进化的原材料;自然选择决定生物进化的方向。
The examination of the theory of modern biological evolution, from the past three years all over the country entrance exam papers, the amount gradually increased, the question type from a single multiple choice questions into multiple choice questions and short answer questions. In order to make students understand systematically the main contents of modern biological evolution theory and get familiar with the related calculation, the main contents of modern biological evolution theory and the calculation related to gene frequency are summarized as follows. First, the main content of modern evolutionary theory Population is the basic unit of biological evolution; mutation and gene recombination produce the evolution of raw materials; natural selection determines the direction of biological evolution.
