我读了周崙在“生物学通报”1955年2月号发表的“关于獲得性遗传的问题”,就获得性为什么有时会不显著,也就是说获得性能够遗传,但不一定全可遗传。周仑先生在解释这个现象时,他所指出的两點原因,都不外是新性状是否影响到性器官的新陈代谢;是否以某一定程度去改变性细胞的形成特性。只强调了生物有机体的遗传特点,而忽视遗传基础还要具备一定外界条件——引起变异的条件——的作用才能实现,不难设想,如果有机体的某一种或某些性状,更具体的说某些後天获得性状和特性,对其生殖细胞的新陈代谢作用发生了强烈的影响,引起了性细胞特性的改变。这样看来,获得性就能遗传下去。但是如果在後代中,缺乏了引起这些性状、特性发生的原因,获得性就不能表现出来,也会成为不显著现象。正如孟德尔-摩尔根论客们常举的“运年
I read the article “Questions about acquired heredity” published by Zhou Lun in the Bulletin of Biology in February 1955, why acquisition sometimes is insignificant, that is to say, acquired sexual heredity but not necessarily heritable . Mr. Zhou Lun explained the phenomenon, he pointed out two reasons are nothing more than whether the new traits affect the metabolism of sexual organs; whether to some extent to change the formation of sex cells. Only emphasized the genetic characteristics of biological organisms, while ignoring the genetic basis but also have some external conditions - caused by the conditions of variation - the role can be achieved, it is not difficult to imagine that if a certain organism or certain traits, more specific To say that certain acquired acquired traits and traits have a strong effect on the metabolism of their germ cells has caused a change in the properties of the sex cells. In this way, access will be inherited. However, if there is a lack of reasons for the occurrence of these traits and characteristics in future generations, the acquiredness can not be demonstrated and will become an insignificant phenomenon. As Mendel-Morgan regularly lifted the “transport year.”
