查询词典 telocentric

The karyotype pattern showed that the chromosome number of 2n = 48 contained two metacentric chromosomes, two submetacentric chromosomes, 44 telocentric chromosomes. The karyotype formula is 2 m + 2 st + 44 t and the fundamental number is 52. We will continue to make the karyotype analysis of other tunas in the future.

NO.1 chromosome was submetacentric,NO.2 and Z chromosome were metacentric,and the others were telocentric,which was slightly different from the results of others. Additionally,analysis of G-banding patterns for macrochromosomes indicated that they were divided into 27 zones and 134 bands.

染色体形态分别为：NO.1染色体为sm型，NO.2、Z染色体为m型，其余染色体均为t型，这与前人研究结果存在一定差异。G带分析结果显示，鹌鹑的前9对大染色体及Z、W染色体G带可分为27个区，134带。

The number of the chromosomes in Henan large tail sheep is 2n=54, the karyotypes of male and female sheep are 54, XY and 54, XX, respectively. There are 26 pairs of autosomes and 1 pair of sex-chromosome. Among 26 pairs of autosomes, 3 pairs are metacentric chromosomes, 23 pairs are telocentric chromosomes. X chromosome is the biggest subtelocentric chromosome and Y chromosome is the smallest submetacentric chromosome.

河南大尾寒羊二倍体染色体数目为2n=54，公羊核型54，XY；母羊核型54，XX.27对染色体中包括26对常染色体和1对性染色体，常染色体中有3对为中着丝粒染色体，23对为端着丝粒染色体；性染色体中，X染色体为最大的端着丝粒染色体，Y染色体为最小的中着丝粒染色体。

Primary culture and subculture were adopted using lung cells of a female Elaphodus cephalophus' embryo. A new karyotype and a pair of big telocentric chromosomes were found. The diploid has 48 chromosomes, and the karyotype formula is 2M+2ST+42T+XX. C-banding analysis shows that these chromosomes are homologous with those reported relevant chromosomes. This article is the first to report the polymorphism of Elophodus cephalophus B-chromosomes and studies it's transmitted mechanism.

采用原代培养和传代培养法，对1头毛冠鹿的胚肺组织细胞进行观察，发现一种新的核型，其二倍体染色体数目为2n=48，核型公式为2M+2ST+42T+XX，出现1对大的末端着丝粒染色体，C-带显示该染色体与已报道的相关染色体同源，首次提出毛冠鹿B染色体多态，对其传递机制进行了探讨。

Besides, NO.4, 6, 8, Z chromosome of domestic fowl were submetacentric, submetacentric, metacentric, metacentric, repectively, whereas those of quail were all telocentric.

结果表明，家鸡和鹌鹑染色体数目均为2n=78，但染色体的形态存在明显差异，主要表现在NO.1、NO.4、NO.6、NO.8和Z染色体上。

Software and results were saved in EXCEL for consequent statistic operation and obtaining chromosome patterns. 4 indexes were chose, such as chromosome karyotype, C-band pattern, chromosome behavior and B chromosome for comparative analyses, and adopted SPSS to reconstruct dendrogram. Combined with studies on insect morphology and insect geography, we made a detailed analysis and speculation on the relationship of taxa concerned. Finally we got the conclusions as follows: 1. The number of chromosomes in grasshoppers of Oedipodiae is 2n 〓=23=22+XO. All chromosomes are telocentric chromosomes. Most of the genome formulas are 3L+6M+2S+X and 3

论文选取染色体核型、C-带带型、染色体行为和B染色体这4个方面的指标进行比较分析，运用SPSS系统分析软件建立表达各属和各种之间亲缘关系的系统树，并结合昆虫形态学和昆虫地理学等方面的研究成果，对其亲缘关系进行了比较详细的分析和推测，得出以下结论：一、斑翅蝗科蝗虫的染色体数目都稳定在2n〓=23条，性别决定机制是XO型，染色体均为端部着丝粒，染色体组式以3L+6M+2S+X和3L+7M+1S+X这两种类型为主，即3对大型染色体，6～7对中型染色体和2～3对小型染色体，X染色体以中型为主，在染色体组中主要排列为4～7位。
