摘要
以尾纹裸头虎鱼的脾脏细胞为材料,用空气干燥法制片,进行其染色体组型分析。染色体数目2n为44,染色体总臂数(NF)为86,其中中部着丝点染色体为10对,亚中部着丝点染色体为11对,端部着丝点染色体只1对,即2n等于20m+22sm+2t。
The karyotype of Chaenogobius annularis was studied through the chromosome metaphase prepared from spleen cells by the PHA-colchicine-hypotonic-air drying technique and Giemsa staining. The diploid chromosome number of Chaenogobius anularis was found to be 2n=44. Its karyotype comprises 10 pairs of metacentric chromosome, 11 pairs of submetacentric chromosome and 1 pair of telocentric chromosome. Its fundamental arm number (NF) is 86.
