中文摘要 | 本文旨在探討泥鰍 Misgurus anguilicaudatus、斑馬魚Brachydanio rerio、牡蠣Crassostrea gigas 與文蛤 Meretrix lusoria 核型的製作與分析。試驗 係以胚體為材料,取其細胞分裂旺盛,容易取得分裂中期Metaphase 細胞的優 點。研究結果發現,泥鰍的染色體數2n=48,包含二對 Metacentric,八對 Submetacentric,一對 Subtelocentric,其餘十三對是Telocentric。斑馬魚的染色 體數也是2n=48,包含三對 Metacentric,十七對Submetacentric 與四對 Subtelocentric。至於牡蠣其染色體數目2n=20,包括十對Metacentric。而文蛤 染色體數2n=50 ,分別為十對 Metacentric,十四對Submetacentric 與一對的 Subtelocentric 者。 |
英文摘要 | The karyotypes of loach Misgurus anguilicaudatus, zebra fish Brachydanio rerio, oyster Crassostrea gigas and hard clam Meretrix lusoria were obtained using embryo chopping method. The diploid chromosome numbers of each species are as follows, (a) loach: 48, including 2 pairs of metacentric, 8 pairs of sub- metacentric, 1 pair of subtelocentric, and the other 13 pairs are telocentric chromosomes; (b) zebra fish: 48, including 3 pairs of metacentric, 17 pairs of submetacentric, 4 pairs of subtelocentric ones; (c) oyster: 20, including 10 pairs of metacentric ones; (d) hard clam: 50, including 10 pairs of metacentric, 14 pairs of submetacentric and 1 pair of subtelocentric ones. |
