| 摘 要： | 我们以大平二号蚯蚓为材料,采用空气干燥制片法对蚯蚓的染色体组型进行了研究。初步结果证实,大平二号蚯蚓的染色体数目2n=22。其中有5对中部着丝点染色体,1对亚中着丝点染色体,2对亚端着丝点染色体和3对端部着丝点染色体。由于蚯蚓为雌雄同体动物,在组型分析的基础上,我们认为不存在性染色体。

The Analysis of Karyotye in Earthworm (Ohira 2) |
| |
| Abstract: | The Karyotype of Ohira 2 has been studied by means of airdried technique. Preliminary studies demonstrated that Ohira 2 had all 2n=22 chromosomes, of which five pairs are metacetric, one pair sub-metacentric, two pairs sub-telocentric and three pairs telocentric. On the basis of Karyotypical analysis it was considered there were no sex-chromosomes in earthworm as it is a hermaphrodite. |
