Abstract

C-band patterns of some Odontophrynus species from Brazil are described. O. americanus 2n and 4n are cryptic species similar to O. cultripes 2n, but their C-banding patterns are different. In O. americanus 2n the C-band appears at the secondary constriction of chromosomes 4. In O. americanus 4n and O. cultripes the C-band appears at the secondary constriction of chromosomes 11. O. cultripes chromosomes 2,3 and 6, have also an intercalary band. Furthermore, fine centromeric bands in several weeks old preparations of these species were observed. The possibility of a structural or chemical heterogeneity of those heterochromatic regions is discussed.

摘要

描述了来自巴西的一些齿蟾属物种的C带模式。美洲齿蟾2n和4n是与2n的栉趾蟾相似的隐存种，但它们的C带模式不同。在美洲齿蟾2n中，C带出现在第4号染色体的次缢痕处。在美洲齿蟾4n和栉趾蟾中，C带出现在第11号染色体的次缢痕处。栉趾蟾的第2、3和6号染色体也有居间带。此外，在这些物种几周龄的制片中观察到了精细的着丝粒带。讨论了这些异染色质区域存在结构或化学异质性的可能性。
