| 摘 要： | 采用空气干燥和胰酶消化法,对黄鳝体内新棘衣棘头虫Pallisentis(Neosentis)celatus]的染色体核型和G-带进行研究,结果表明,新棘衣棘头虫由3对常染色体和1对性染色体组成,其中X染色体和1号、3号都为中着丝粒染色体,2号为亚中着丝粒染色体,Y为端着丝粒染色体,核型公式为2n=5m+2sm+1t;性别决定模式为XX-XY;每对染色体都有特定的G-带带型.

| Abstract: | It is the first time to study the karyotype and G-binding of the Pallisentis (Neosentis) celatus in the Monopterus albus by using air drying method and pancreatin digestion. Results: The karyotype of Pallisentis (Neosentis) celatus consists of three autosomal biarmed chromosomes and two X chromosomes in females or one X and one Y in males. There are three pairs metacentric chromosomes, NO1, NO3 and X chromosome. NO2 are submetacentric. The Y is the only telocentric chromosome. The sex determining mechanism is of the XX-XY type. Every pair of chromosomes had their characteristic G-banding pattern. And this paper will be useful for the cell genetics and taxonomy of Pallisentis (Neosentis) celatus. |
