核型

Taken together, compared with the susceptible strain, the resistance strai ns have no obvious changes in karyotype but have distinct difference in DNA level, which suggests that insecticide resistance is related to the changes hi gen omic DNA in diamondback moth.

从上面的结果看来，与敏感品系相比，三种抗性品系小菜蛾的核型没有发生明显的变化，但在DNA水平上存在明显的差异，说明小菜蛾的抗药性与基因组DNA的变化有关。

The chromosome genomes of Deqin wild alfalfa variety (Medicago sativa L.), scattered alfalfa variety (AC-3) in Yunnan province and 8 foreign introduced cultivated alfalfas were classified and compared by karyotypic analysis.

以云南野生种紫花苜蓿、逸散种紫花苜蓿(AC-3)和8个国外引进栽培种紫花苜蓿为材料，采用核型分析方法对供试材料的染色体组进行了分类和比较。

In Klinefelter's syndrome however, due to one of nature's accidents, when the male sperm fuses with the female egg, the fetal cells have at least one extra X chromosome. The most common number of chromosomes found in KS is 47, that is 44 autosomes and 3 sex chromosomes giving a karyotype of 47,XXY.

在克氏综合徵，但由於一大自然的意外，当男性的精子导火索，与女性卵子，胎儿细胞有至少一个额外的X染色体是最常见的染色体数目，发现在堪萨斯州是47 ，这是44 autosomes和三性染色体给予染色体核型47 ， xxy 。

X chromosome was a large submetacentric chromosome. Y chromosome was a small metacentric chromosome.The relative length of chromosome was measured by AutoCAD software. The relative length of autosomes ranged from 1.545% to 4.921% in Yanbian yellow cattle and from 1.637% to 5.855% in Liyan hybrid cattle.

结果表明，延边黄牛和利延杂交牛二倍体染色体数目2n=60，公牛核型为2n=60，XY，母牛为2n=60，XX，其中29对常染色体均为端着丝粒染色体，X染色体为较大的亚中着丝粒染色体，Y染色体为较小的中着丝粒染色体。

When applied the spiny eel X chromosome library probes to the chromosomes of the two fish, different signals were distributed: in Siniperca chuatsi, besides some little signals on lot of autosomes, a large bright signal region was detected on the 8th chromosomes, which represented a synteny of spiny eel X chromosomes; but in Channa argus, no distinct synteny was found.

当以刺鳅的生物素标记X文库探针对鳜鱼和乌鳢的有丝分裂染色体进行染色体涂绘后，经过核型分析和统计分析表明，在这两种鱼的染色体上的杂交信号分布是不同的：在乌鳢中，除散在信号外，在其第八号染色体近着丝粒部位存在着一段较大的信号结合区域，应是与刺鳅的X染色体同源的保守同线群，而在鳜鱼中，只有散在信号分布于多条染色体上，没有明显的保守同线群存在。

The configuration of metaphase chromosome; three kinds of functional elements about chromosome DNA; karyotype and chromosome bandings; giant chromosome.

三 中期染色体的形态结构；染色体DNA的三种功能元件；核型与染色体显带；巨大染色体。

The results indicate that at least 28 fissions, 49 fusions and 4 inversions were needed to"convert" the dog karyotype to that of the red panda, suggesting that extensive chromosome rearrangements differentiate the karyotypr of red panda and dog.

结合已发表的狗与家猫的比较染色体图谱，我们推测：小熊猫与家猫之间共存在26个同源片段，二者的核型之间显示了较高的同源性。
