一、考情分析生物育种是利用遗传学、工程学、生理学等方法原理培育生物新品种的过程。目前,生物育种的技术和方法主要有:杂交育种、诱变育种、单倍体育种、多倍体育种、植物激素育种、基因工程育种、细胞工程育种和胚胎工程等,这些育种知识蕴藏在高中生物课本相关章节的“应用内容”的叙述中。随着生物科学技术的发展和进步,生物育种已经深入到个体、细胞、分子等不同层次水平。综合近5年的高考试题,北京、上海、广东、江苏等地试卷中频繁考查与育种密切相关的知识。通过归纳、比较不难发现,高考试题关于生物育种知识的 First, the test analysis Biological breeding is the use of genetics, engineering, physiology and other methods to cultivate new varieties of biological processes. At present, the techniques and methods of biological breeding are mainly hybrid breeding, mutagenesis breeding, haploid breeding, polyploid breeding, plant hormone breeding, genetic engineering breeding, cell engineering breeding and embryo engineering, which are contained in high school Biology textbook related chapters “application content ” narrative. With the development and progress of biological science and technology, biological breeding has gone deep into different levels such as individuals, cells and molecules. Comprehensive examination of nearly five years of college entrance examination papers in Beijing, Shanghai, Guangdong, Jiangsu and other places in the frequent examination and breeding of closely related knowledge. Through induction, more difficult to find, college entrance examination questions on biological breeding knowledge
