Y-chromosome is a middle-sized acrocentric. Y为中型近端着丝粒染色体。
The result showed that all autosomes which have short arm were acrocentric, the X and Y chromosomes were submetacentric. 结果是牦牛常染色体均为近端点着丝粒染色体,X、Y染色体为亚中部着丝粒染色体。
Y chromosome has two types of polymorphism:metacentric (or submetacentric) and acrocentric chromosomes. 染色体有中部(或亚中部)和近端着丝粒染色体。
The X chromosomes were all submeta-centric and the Y chromosomes were acrocentric in five breeds. X染色体均为近中着丝粒染色体,Y染色体为近端着丝粒染色体。
The diploid chromosome number is 2n = 66. The autosomes consist of 8 meta-, 16 submeta-, 6 subtelo-, and 2 acrocentric pairs. 常染色体由8对中着丝粒染色体、16对亚中着丝粒染色体、6对亚末端着丝粒染色体及2对近端着丝粒染色体组成。
Methods:By the method of Ag-NOR,the NOR and acrocentric association were studied in 30 male drug addicts and 30 normal men. 方法 :采用Ag -NOR技术 ,分别对 30名男性吸毒患者和 30名正常男性的NOR及近端着丝粒染色体联合进行了初步研究。
