1疑问胡香荣[山东省沾化县第二中学(256800)]人教版高中《生物·必修2·遗传与变异》对“染色体组”的定义是:“细胞中的一组非同源染色体,在形态和功能上各不相同,携带着控制生物生长发育的全部遗传信息,这样的一组染色体,叫做一个染色体组”。该定义在2008年以后印刷的教材改为:“细胞中的一组非同源染色体,在形态和功能上各不相同,但又互相协调,共同控制生物的生长、发育、遗传和变异,这样的一组染色体,叫做一个染色体组”。上述概念的变化,对中学教学究竟有哪些启示呢?
1 Question Hu Xiangrong [Zhanhua County No.2 Middle School in Shandong Province (256800)] PEP High School’s “Biological · Compulsory 2. Genetic and Variational” definition of “genome” is: “A group of cells in the same group are different The source chromosomes are different in morphology and function, carrying all the genetic information that controls the growth and development of organisms. Such a group of chromosomes is called a chromosome group. The textbook that was defined after 2008 was changed to: ”A group of non-homologous chromosomes in cells that differ in form and function but coordinate with each other to jointly control the growth, development, inheritance, and variation of the organism. This group of chromosomes is called a chromosome group." What are the implications of the above-mentioned changes in the concept of secondary education?
