在表现出明显世代交替的生物体中，配子可能是由单倍体世代发生有丝分裂产生，亦可由二倍体世代减数分裂直接产生配子体或配子母细胞。

By Giemsa--C technique, the chromosomes of Aegilops tauschii (85A-34) and Hordeum vulgare (H2) and Ae.tauschii- H.vulgare amphidiploid were all produced clear bands, the terminal band, centromeric band, secondary constrition band and rich intercalary bands were displayed distinctly, thus the corresponding Giemsa-C banding patterns were confirmed.

利用Giemsa--C带显带技术，节节麦、大麦、节节麦-大麦双二倍体都显示出了清晰的带纹，都具有端带、着丝点带、随体带和丰富的中间带，相应的确定了它们的Giemsa--C带核型。

The biological analysis results showed: Population Doubling Time of cells was approximately 24 h;Diploid account for 76%～88% in cell's chromosome;By Isozyme analysis of Lactic Dehydrogenase,Malic Dehydrogenase,cross contamination had not taken place;The test results of ...

结果表明：细胞群体倍增时间约为24 h；细胞染色体中二倍体(2n=60)占主体，镜检细胞的百分比为98.2%；乳酸脱氢酶、苹果酸脱氢酶同工酶分析，没有其他物种污染；细菌、真菌、病毒、支原体检测阴性。

In addition,the satellitic numbers and satellitic heterozygosity of diploid species of Paeonia in China are briefly discussed.

此外，对国产芍药属二倍体种的随体数目及其杂合性等问题进行了初步讨论。

Results: miR27a was identified as the most stable reference gene by geNorm and Normfinder software. Among the 52 microRNAs detected by real time PCR array, miR-33 and miR-19a were significantly down-regulated, whereas miR-130 were significantly up-regulated in the hippocampus of Ts65 Dn mice as compared with the euploid control mice. The expression of miR-802, which was the trisomy chromosome 16 derived microRNAs, was very low in hippocampus with no difference between the two groups.

结果：geNorm和Normfinder两种方法均选定miR-27a为最稳定的内参照基因，共检测了52种microRNAs，其中miR-33和miR-19a在Ts65Dn小鼠海马组织中表达显著下调，miR-130在Ts65Dn小鼠海马组织中表达显著上调，小鼠16号染色体三体区段包含的miR-802在Ts65Dn小鼠和对照二倍体小鼠海马组织中表达量均低，差异没有统计学意义。

To induce diploid gynogenesis in summer flounder, eggs were fertilized with heterogenous cryopreservative sperm of Lateolabrax japonicas , which was irradiated with UV ray to be genetically inactivated, and cold shock was used to prevent extrusion of the second polar body.

中文摘要：用冷冻保存的花鲈精子作为异源精子，采用紫外线对精子进行照射使其遗传物质失活，然后与卵子进行"授精"，可以刺激犬齿牙鲆鱼卵进行雌核发育，在受精后一定时间采用冷休克处理"授精"卵，抑制第二极体排出成功获得了犬齿牙鲆雌核发育二倍体鱼苗。

Any of various mixtures of xylidine isomers.An organism that is haploid throughout its life cycle except as a zygote, when it is diploid, as in many algae and fungi.

单元体一种在其整个生命循环过程中保持单倍体，而只有在海藻或真菌中作为合子才呈现二倍体状态的生物组织

The basic concept of FOP can be summarized as to further optimize effective prescription according to the standard of curative effects and with the aid of modern science and technology and theories of traditional Chinese medicine.

其基本内涵可概括为：以确有疗效的中药复方为研究对象，以现代科学技术和传统中医药理论为技术支持，以该复方所治病证的药效响应为评价标准，以优化重组疗效更优的新复方为研究目的。
