前两天看央视农业发的一个视频,说把耐热基因导入到玉米中,培训耐热玉米新品种。评论区炸锅了,转基因转基因转基因。更有甚者口口声声说自己学生物的,这就是转基因,非蠢即坏。甚至有可能是老美雇的水军。我拿一个耐热的玉米和不耐热的玉米一直做杂交,后代总会出现产量高,品质好,又耐热的天选之子。就是大家常说的中了基因彩票。实际上就是通过不停的回交,把耐热基因导入到各方面都好,唯独耐热是短板的玉米品种中。而且玉米杂交育种的厉害之处在于,爸妈可能都平平无奇的,甚至很差,但后代就是品质优,产量高的情况。(学名叫玉米杂种优势)PS.以前生物书转基因抗虫棉把bt毒蛋白的概念给大家太深印象了,导致都过了二十年,某些别有用心之人还拿bt毒蛋白说事儿。
