Abstract
The present study depicts the phenomenon of supernumerary chromosomes as autonomous genome elements, similar in features with segmental duplications. Possible role of B chromosomes in evolution and the reasons of their nonrandom distribution in different mammalian taxa are discussed.
摘要
本研究将超数染色体现象描述为自主基因组元件，其特征与片段重复相似。文中讨论了B染色体在进化中的可能作用以及它们在不同哺乳动物类群中非随机分布的原因。
