例析基因型频率与基因频率的计算

Example analysis of genotype frequency and gene frequency calculation

基因频率与基因型频率的知识是高中生物必修二教材第七章的教学重点和难点内容,生物进化的实质就是种群基因频率的改变。本文通过一道例题的计算,让学生学会在连续自交、自由交配等情况下基因型频率和基因频率的多种计算方法,认识并理解到生物进化的实质。

the knowledge of gene frequency and genotype frequency is the key and difficult content of the seventh chapter of the high school biology compulsory second textbook. The essence of biological evolution is the change of gene frequency of population. Through the calculation of an example, this paper allows students to learn a variety of calculation methods for genotype frequency and Gene frequency in the case of continuous self-intercourse, free mating, etc., and to understand and understand the essence of biological evolution.
