一.引言有机体在繁殖过程中,通过生殖细胞(有性繁殖)或营养体(无性繁殖),把亲代的遗传特性传递给子代,使每种生物表现了一定的遗传性。但是任何性状不能直接由生殖细胞或营养体传递给子代,它是在一定物貭基础上通过个体发育而表现出来的。那么生物的性状究竟借什么而遗传呢?到底有没有遗传物貭?它的性貭怎样?这个问题一直是生物科学上争论的焦点之一。
I. INTRODUCTION Organisms pass on the germline (sexual reproduction) or vegetative (vegetative) during reproduction to pass on the genetic characteristics of their parents to their offspring, rendering each organism a certain hereditary. However, any trait can not be passed on directly to the offspring by germ cells or vegetative organs, and it is manifested through individual development on the basis of certain things. So what kind of biological traits by what genetic? In the end there is no genetic material? Its sexual? How? This issue has been the focus of controversial biological science.
