%X 以骨髓细胞为材料研究赤链蛇的染色体,结果表明该物种2n=46,由8对大型的和15对微小的染色体组成,AF=50.性染色体的大小介于3号和4号之间,为ZW型;8对大型染色体均显示着丝粒C带,1-6号还显示浅染端粒C带.W染色体为整条C带阳性;该物种一对NOR位于7号染色体近着丝粒区.不同地理分布群赤链蛇核型可能经历过Z与W染色体不等交换。 Abstract:The Karyotype,C-bands and Ag-NORs of Dinodon rufozonaturn (Cantor) reported is in this paper including the diploid number(2n=46)comprising 8 pairs of macro-and 15 pairs of microchromosomes,and AF=50 in the D.rufozonatum.The sex chromosome in size locates between the autochromosones No.3 and No.4,which belongs to ZW type.The C-banding technique revealed that the all macrochromosomes there are centromerc C band,the telomeric C band was only observed in Nos.1~6,while a whole W chromosome is constitutive heterochromatinization.Two NOR were observed on the pericentric of the No.7 chromosome.
