美《纽约时报》1980年5月18日报道Robert D.MeFadden文章:染色体是在人体各细胞核内发现的极小的线状体,同样在多数动物及植物细胞内都有。染色体以基因形式携带遗传信息,确定一个机体的生长、发育及其特征。人类的每个细胞有46个染色体——一对确定性别,22对控制其它特征的遗传。当细胞生长和分裂繁殖时,新形成的染色体和其基因正常对原物作了很准确、完全和十分完善的复制。这种明显忠实的再繁殖能力说明种系代代相传的延续性。
The United States of America The New York Times reported on May 18, 1980 Robert D. Meadad article: Chromosomes are tiny, linear bodies found in every nucleus of a human body, also found in most animals and plant cells. Chromosomes carry genetic information in their genetic form to determine the growth, development, and characteristics of an organism. Each human cell has 46 chromosomes - one for sex and 22 for inheritance of other traits. When cells grow and divide, the newly formed chromosomes and their genes make a very accurate, complete and perfect copy of the original. This apparent faithful ability to reproduce shows the continuity of the germ line from generation to generation.
