| 摘 要： | 采用常规骨髓细胞制片法,对黑龙江省产黑龙江草蜥和白条草蜥的染色体组型进行分析.结果表明,两种草蜥二倍体染色体的数目均是38,由18对常染色体和1对性染色体组成.常染色体中17对为端部着丝点染色体,1对为点状染色体;性染色体为ZW 型,从核型特征看来,二者都为蜥蜴目较原始的类型.

| Abstract: | The karyotypes of Takydromus amurensis and T.wolteri from Heilongjiang Province were examined using medulla cells and the colchicine-hypotonic air-dry technique.The results showed that the number of diploid chromosomes in the two species was 38 and were composed of 18 pairs of euchromosomes and a pair of sex chromosome,including 17 pairs of telocentric chromosomes and a pair of spot chromosomes.The sex chromosome was of the type ZW.According to karyotypic characteristics,they are all primitive species withi... |
