Abstract

The aim of this study is to produce G-banded karyotypes of three dolphin species, Montagu, 1821, Charlton-Robb et al., 2011, and Cuvier, 1812, and to determine if any differences between the species can be observed. Monolayer skin cultures were established and processed for chromosome study by trypsin banding. The results indicate that the three species here investigated have the same diploid number (2n = 44) and very similar gross chromosome morphology, however G-banding allows distinction between each species. Chromosome 1 in is significantly different from the other 2 species, and chromosome 2 in is subtly different from the other 2 species. This result is of potential significance in taxonomic studies, and can provide an unequivocal answer in the assessment of suspected hybrids between these species.

摘要

本研究的目的是制作三种海豚物种（1821年的蒙塔古海豚、2011年的查尔顿 - 罗布等人描述的海豚以及1812年的居维叶海豚）的G带核型，并确定是否能观察到这些物种之间的任何差异。建立了单层皮肤培养物，并通过胰蛋白酶显带法进行染色体研究。结果表明，这里研究的三种物种具有相同的二倍体数（2n = 44）和非常相似的总体染色体形态，然而G带能区分每个物种。[此处原文缺失具体物种名称]的1号染色体与其他两个物种有显著差异，[此处原文缺失具体物种名称]的2号染色体与其他两个物种有细微差异。这一结果在分类学研究中具有潜在意义，并能为评估这些物种之间疑似杂交种提供明确答案。
