A study of the incidence of chromosome instability in the Japanese quail as assessed by sister chromatid exchange (SCE) and fragile site identification in chromosomes was conducted in two parent breeds and their F1 and F2 generations. 2. The mean incidence of SCEs was 6.02 ± 0.45 and the frequency of fragile sites was 1.17 ± 0.79. 3. There were moderately negative correlations of 0.51-0.64 between chromosome instability and fertility in the F1 and 0.10-0.23 in the F2. The hatch of fertilised eggs was negatively correlated with the number of SCE in male (0.31) and female (0.33) F1 and was lower in P (0.18 and 0.19, respectively), whereas the correlations were similar for the number of fragile sites in both generations (0.51-0.62).

通过姐妹染色单体交换（SCE）和染色体脆性位点鉴定，对日本鹌鹑染色体不稳定性的发生率进行了研究，研究对象包括两个亲本品种及其F1和F2代。2. SCE的平均发生率为6.02±0.45，脆性位点的频率为1.17±0.79。3. 在F1代中，染色体不稳定性与育性之间存在中度负相关，相关系数为0.51 - 0.64；在F2代中，相关系数为0.10 - 0.23。受精卵的孵化率与F1代雄性（0.31）和雌性（0.33）的SCE数量呈负相关，在亲本中较低（分别为0.18和0.19），而两代中脆性位点数量的相关性相似（0.51 - 0.62）。
