Abstract
B chromosomes (Bs) are supernumerary to the standard chromosome set, from which they prevalently derive. Variation in numbers both among individuals or populations and among cells within individuals is their constant feature. Leisler's bat Nyctalusleisleri (Kuhl, 1817) is one of only four species of Chiroptera with detected Bs. Four males of N.leisleri were collected from two localities on the territory of Serbia and cytogenetically analysed. All animals had Bs with interindividual variability ranging from two to five heterochromatic micro Bs. The highest number of Bs was detected in this species. Among mammals, Rodentia and Chiroptera are orders with the largest number of species, but Bs frequently appear in rodents and rarely in chiropterans. Possible explanations for this difference are offered.
The Leisler's bat Nyctalusleisleri (Kuhl, 1817)中B染色体数目最高的新发现。
B染色体(B)是额外的标准染色体集，他们普遍来自。个体之间或群体之间以及个体内部细胞之间的数量变化是它们的恒定特征。Leisler's bat Nyctalusleisleri (Kuhl, 1817)是仅有的4种检测到b的翼翅目蝙蝠之一。在塞尔维亚境内的两个地点采集了4只雄性莱斯利奈瑟螨，并进行了细胞遗传学分析。所有动物都有b，个体间变异范围从2到5个异色微b。在该物种中检测到的Bs数量最多。在哺乳动物中，啮齿目和翼手目是种类最多的目，但b在啮齿目中出现较多，在翼手目中较少。对这种差异给出了可能的解释。
