The karyology of the partridges Francolinus francolinus asiae (2n = 70) and F. pondicerianus interpositus (2n = 68) and the Japanese quail Coturnix coturnix japonica (2n = 78) was investigated. The frequency distribution of the diploid number of chromosomes was tabulated and the most frequent number was taken to be the diploid number. All species showed a bimodal karyotype and the variation in the number of chromosomes was attributed to the macrochromosomes, although twelve macrochromosomes were present in all the species. Female heterogamety revealed that ZZ male:ZW female sex chromosome mechanism was present. The structure and behaviour of chromosomes during mitosis are described and the evolution of karyotype and cytotaxonomic considerations discussed.
对鹧鸪属的南亚鹧鸪（2n = 70）、灰头鹧鸪（2n = 68）以及日本鹌鹑（2n = 78）的核型进行了研究。将染色体二倍体数目的频率分布制成表格，并将最常见的数目视为二倍体数。所有物种均呈现双峰核型，尽管所有物种都有12条大染色体，但染色体数目的变化归因于大染色体。雌性异配揭示了存在ZZ雄性：ZW雌性的性染色体机制。描述了有丝分裂过程中染色体的结构和行为，并讨论了核型的进化和细胞分类学方面的考虑。
