生物育种是一门很复杂的技术,在生产实践中具有极大的用途。生物的培育过程涉及对遗传、变异等知识的综合理解与应用,对此知识点的考查符合“注重与现实生活的联系”的新课程理念,一直是高考的重点、热点,各地的单科卷和理综卷均能找到它们的“身影”。下面从复习的有效性角度,对本部分知识进行归纳及例析。高中生物中涉及的育种有:基因工程育种、细胞工程育种、单倍体育种、多倍体育种、 Bio-breeding is a very complex technology and has great uses in production practice. The cultivation process of organisms involves the comprehensive understanding and application of genetics, variation, and other knowledge. The examination of this knowledge point is consistent with the new curriculum concept that focuses on the connection with real life, and has always been the focus and hot spot of the college entrance examination. Both the roll and the compound roll can find their shadows. The following section summarizes and analyzes the knowledge of this section from the perspective of the validity of the review. The breeding involved in high school biology includes genetic engineering breeding, cell engineering breeding, haploid breeding, polyploid breeding,
