The chromosome number is 2n=96, belonging to hexaploid species (2n=6x=96), and the morphological difference is not obvious among the 96 chromosomes. All the chromosomes are metacentric and submetacentric. Relative length ratio of the longest to the shortest chromosomes is 2.10. There is no satellite chromosome in all the 96 chromosomes. The karyotype formula is 2n=96=60m+36sm, the karyotype type is 2B, a higher karyotype evolution.
结果表明,该入侵种的染色体数为2 n=96,属六倍体物种,各染色体间形态差异不明显,均为中着丝粒或近中着丝粒染色体,最长与最短染色体相对长度比为2.10,全套染色体未见随体,核型公式为2 n=96=60 m+36 sm,核型类型为进化程度较高的2B型。

Second Municipal People's Hospital of Guangzhou, Guangzhou 510150 Objective To study the technique and diagnostic value of fluorescence insitu hybridization in chromosome abnormality for prenatal diagnosis. Methods Amniocenteses were performed in 34 pregnant women of 16~23 gestational weeks with indications for prenatal diagnosis. The amniotic fluid samples were cultured in Chang's medium.
对34例孕16~23周有产前诊断指征者经腹部抽取羊水,用Chang培养液传代培养,常规制备羊水细胞分裂中期染色体,应用生物素及地高辛标记的人类全着丝粒探针和X、Y、13、21、18号染色体α-着丝粒探针及染色体全涂染探针,与培养的羊水细胞分裂中期染色体DNA进行原位杂交,杂交后用荧光显微镜观察玻片并摄像。

Methods Amniocenteses were performed in 34 pregnant women of 16~23 gestational weeks with indications for prenatal diagnosis. The amniotic fluid samples were cultured in Chang's medium. The metaphase chromosomes were hybridized insitu with the human centromere probes,α-satellites DNA probes of X, Y,13, 21, 18 chromosomes and all primer chromosome probes. These probes were conjugated by Biotin and Dioxin then. The treated slides were examined and taken photos under the fluoromicroscope.
