The Houbara bustard Chlamydotisundulata (Jacquin, 1784) is an emblematic and endangered bird of steppes and desert spaces of North Africa. This species belonging to Otidiformes is recognized as vulnerable by the International Union for Nature Conservation. The critical situation of this species and the revision of its classification on the tree of birds encouraged the authors to start accumulating chromosome data. For that, we propose the GTG- and RBG-banded karyotypes of the Houbara bustard prepared from primary fibroblast cell cultures. The first eight autosomal pairs and sex chromosomes have been described and compared to those of the domestic fowl Gallusdomesticus (Linnaeus, 1758). The diploid number has been estimated as 78 chromosomes with 8 macrochromosomes pairs and 30 microchromosomes pairs, attesting of the stability of chromosome number in avian karyotypes. The description of the karyotype of the Houbara is of crucial importance for the management of the reproduction of this species in captivity. It can be used as a reference in the detection of chromosomal abnormalities, which would be responsible of the early embryonic mortalities.

脆弱物种厚巴拉bus（Otidiformes）的带状细胞遗传学和与家禽的比较分析。

霍巴拉bus鸟Chlamydotisundulata（Jacquin，1784）是北非草原和沙漠地区的象征性濒危鸟类。国际自然保护联盟承认属于兽形目的该物种是脆弱的。该物种的严峻形势及其在鸟类树上分类的修订，鼓励作者开始积累染色体数据。为此，我们提出了从原代成纤维细胞培养物中制备的Houbara t的GTG和RBG带状核型。已经描述了头八个常染色体对和性染色体，并将其与家禽鸡（Gallusdomesticus）的染色体进行了比较（Linnaeus，1758年）。据估计，二倍体数为78条染色体，其中有8个大染色体对和30个微染色体对，证明了染色体核型在鸟类核型中的稳定性。Houbara的核型的描述对于人工饲养该物种的繁殖至关重要。它可以作为检测染色体异常的参考，而染色体异常可能是早期胚胎死亡的原因。
