| 摘 要： | 第1次报道奇异球蛛的核型,包括染色体数目、形态结构、性染色体组成。实验结果表明奇异球蛛染色体数目是:雄体细胞为2n=21,雌体细胞2n=22,性决定机制为XO系统,X染色体为最短的1个(对)。对C-带标本分析表明:所有染色体均为端或亚端丝粒,各染色体有其识别特点。

| Abstract: | This paper reports the karyotype of the T. mirabilis for first time. It involved the chromosomal number .chromosomal form and structure and sex-chromosome components of T. mirahilis. . The experiment material were collected in the suburbs Shijiazhuang. The cylological data were mainly obtained from mitosic metaphase of T. mirahilis is as follows;The somatic cell have 21 chromosomes in the male and 22 chromosomes in the female. It is considered that the machanism of sex-determination is of the XO type. X-chromosomes are the shortest. Analyse of its C-bands shows :all chromosomes seem to consist of telo-or acro-centries. There are middle bands in arm of chromosome. Every chromosome have oneself feature. |
