人体X染色体的显微扫描照片。 (得到照片研究中心允许而复制) X染色体是Y染色体的三倍大,而且也传递着比其多100倍的基因信息。
The X chromosome is three times the size of the Y chromosome and carries 100 times the genetic information.
以外周血淋巴细胞制备染色体标本,人工复合三倍体鲤染色体数为150,其亲本红鲤、红鲫和散鳞镜鲤的二倍体染色体数均为100。
Chromosome preparations made from leucocyte cultures showed that the artificial multiple triploid carp has a chromosomal number of 150, and all the fore parental forms have 100.
研究进一步证明人工复合三倍体鲤与二倍体亲本的染色体倍性和相对dna含量存在着明显的相关性。
Therefore, we have proved that there is a close correlation between the artificial multiple triploid carp and its diploid parents in both chromosomal Numbers and relative DNA contents.
