They are often morphologically distinct from A chromosomes, being smallerand more highly heterochromatic in most cases. B chromosomes do not pair with Achromosomes, and they are inherited in a non-Mendelian way, exhibiting meiotic andmitotic instability and nondisjunction. However, B chromosome DNA is quiteidentical to the corresponding sequence on the A chromosome complement. So far afew B chromosome specific DNA sequence have been identified. Specific DNAsequences on B chromosome have been the attractive research area on Bchromosomes.

现已在千余种植物和近三百种动物中被发现。B染色体与物种中正常染色体不同:独立于整倍体基因组之外,减数分裂时不与A染色体发生联会和配对,细胞分裂后期不分离,非孟德尔遗传,富含异染色质,不含对宿主主要性状有影响的基因等。B染色体DNA的分子组成既与A染色体极为相似,具有A染色体DNA分子组成的一般特征:富含重复序列和转座成分,染色体三大功能组件DNA高度同源;又与之相区别,含有B染色体特异的DNA序列,这些DNA序列可以为探讨B染色体的起源和进化提供有价值的信息。

central element:中央成分

联会复合体:是同源染色体联会过程中形成的非永久性的复合结构,主要成分是碱性蛋白及酸性蛋白,由中央成分(central element)向两侧伸出横丝,使同源染色体固定在一起.

centric fusion:着丝粒融合

罗氏易位通常又称为着丝粒融合(centric fusion). 在减数分裂时,由于由两条短臂构成的小染色体丢失,故在联会时只有三条染色体参与,形成三价体(trivalent)(图2-12). 三价体的分离方式有三种,即交替式(同源着比粒各走向一极,

homologous chromosome:同源染色体

同源染色体(homologous chromosome)是指分别来自父母双方,大小、形态结构基本相同,代谢和遗传功能相似,来源一般都相同的,在减数分裂中联会配对的两条染色体.

non-hygromorphic hygrophyte:非湿生形态的湿生植物

异源染色体联会;异源配对;异型联会 non-homologous synapsis; non-homologous pairing | 非湿生形态的湿生植物 non-hygromorphic hygrophyte | 非同源对偶基因 non-identical alleles

autosyndetic pairing:同源配对

autosynapsis同源联会 | autosyndetic pairing同源配对 | autoteraploid同源四倍体

synapsis:联会

偶线期(zygotene stage)时染色质进一步凝集,同源染色体(homologous chromosomes)发生配对,称为联会(synapsis),所以此期又称配对期(pairing stage). 配对从同源染色体上的若干接触点开始,进而像拉链一样迅速扩展到整个染色体所有的同源片段.
