核型

Due to the breakthrough of stained technology in 1970s, the band-pattern of chromosome provides material visual information for cytogeneticist, then analyses the composition of genome in a cell and measures the features of the equipments for karyotyping.In order to meet the demands of clinical hospital, a chromosome analysis system based on PC is developed.

由于70年代标本染色技术的突破(取代了此前的均匀染色方法，产生了染色体的带型特征)，染色体的带型模式为细胞遗传学家提供了实质性的视觉信息，从而可以进一步分析细胞的基因组的合成以及进行自动核型分类仪器中的特征测量。

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。
