摘要
SCE在鹌鹑胚胎细胞间的分布为Poisson分布;在染色体间的分布是非随机的,与染色体的相对长度成正相关(P<0.05),但也不完全按各染色体的相对长度分布。着丝粒区的SCE相对很高,按染色体的相对长度分布。胚胎的不同性别对每个细胞的SCE平均值无显著影响,但对性染色体Z上的SCE是否有影响还不能做出肯定的结论。
The distribution of SCE among quail embryo cells coincided with Poisson distribution, while among chromosomes, it was nonrandom. There was a positive correlation (P<0.05) between SCE frequency and the chromosomal relative length, but SCE distribution in each chromosome was not completely in accordance with the relative length of each chromosome. The SCE frequency in each centromeric region was very high and accordance with the relative length of each chromosome. The per cell SCE average value was not significantly influenced by the sex of embryo (P>0.05), but that whether the SCE per Z was effected significantly by sex had not been determined.
