| 摘 要： | 采用外周血淋巴细胞培养法和胰酶处理法，对家鸡和鹌鹑染色体的核型和G带进行了研究。结果表明，家鸡和鹌鹑染色体数目均为2n=78，但染色体的形态存在明显差异，主要表现在NO．1、NO．4、NO．6、NO．8和Z染色体上。NO．1染色体，家鸡为m型，而鹌鹑为sm型；NO．4、NO．6、NO．8和Z染色体，家鸡分别为sm、sm、m、m型，而鹌鹑全为t型。G带分析结果显示，家鸡和鹌鹑的G带差异主要反映在NO．1、NO．2染色体上，这可能是由于臂间倒位所致。 |

| Abstract: | Karyotype analysis was carried out on domestic fowls and quails using the peripheral lymphocyte culture techniques and G-banding patterns were obtained with trypsin and Giemsa staining.The results showed that the domestic fowl and quail had a diploid number of 78.But their positions of centromere of macrochromosomes were different from each other.NO.1 chromosome was metacentric,while that of quail was submetacentric.Besides,NO.4,6,8,Z chromosome of domestic fowl were submetacentric,submetacentric,metacentric,metacentric,repectively,whereas those of quail were all telocentric.Additionally,analysis of G-banding patterns for macrochromosomes of them indicated that there was great difference between NO.1 and NO.2 chromosome,which can be explained by the pericentric inversions. |
| Keywords: | domestic fowl quail chromosome karyotype G-banding pattern |
