关于获得性是否可以遗传问题获得性是否能够遗传以及它在生物进化中的地位是两个学派争论很大的另一个中心问题.争论的焦点是在外界环境条件引起生物体发生变异是否能再影响生殖细胞,并通过生殖细胞遗传下去.米丘林学派认为是可以的,而摩尔根学派则认为生活条件只能改变体质,不能改变遗传性,体质变异是不遗传的变异,获得性是不能遗传的,要引起遗传的变异,还必须通过遗传物质基础的改变,而一般代谢作用的强度不足以达到引起基因变化的程度.而生物在异常的生活条件 Whether or not access to genetic problems can be inherited and its place in biological evolution is another central issue of controversy between the two schools and whether the focus of the debate is on whether environmental conditions in the outside world can cause variation in organisms Germ cells, and germ cell inheritance go down. Michurin school that is OK, but the Morgan School believes that living conditions can only change the constitution, can not change the genetic, physical variation is not genetic variation, access is not genetic , To cause genetic variation, but also through the genetic basis of the change, but the general intensity of metabolism is not enough to cause the degree of genetic changes caused by the biological abnormalities in living conditions
