摘要: 分别采用外周血淋巴细胞培养法和胰酶处理法,对鹌鹑染色体的核型和G带进行了研究。结果表明,鹌鹑染色体数目为2n=78,有10对大染色体(包括Z、W),29对小染色体。染色体形态分别为:NO.1染色体为sm型,NO.2、Z染色体为m型,其余染色体均为t型,这与前人研究结果存在一定差异。G带分析结果显示,鹌鹑的前9对大染色体及Z、W染色体G带可分为27个区,134带。

Abstract: Karyotype analysis was carried out on quails using the peripheral lymphocyte culture techniques,and G-banding patterns were obtained with trypsin and Giemsa. The results showed that the quail had a diploid number of 78,with 10 pairs of macrochromosomes including the sex-chromosomes and 29 pairs of microchromosomes. NO.1 chromosome was submetacentric,NO.2 and Z chromosome were metacentric,and the others were telocentric,which was slightly different from the results of others. Additionally,analysis of G-banding patterns for macrochromosomes indicated that they were divided into 27 zones and 134 bands.
