摘要
利用腹腔注射秋水仙素制备肾细胞染色体的方法，对斑尾复鍜虎鱼的染 色体组型和Ｃ－带核型进行了研究。结果表明，其二倍体数目为 ２ｎ＝４４，核型为２Ｍ ＋２ＳＭ＋４ＳＴ＋３４Ｔ＋ＸＹ。Ｘ为端着丝粒染色体，Ｙ为中着丝粒染色体。Ｃ－带核型显 示，每对染色体的着丝粒均具异染色质带，Ｙ染色体的短臂全部为异染色质。
The karyotype of Synechogobius ommaturus has been studied firm the chromosome preparation of kidney cells. The diploid number is 44, The karyotype consists of 1 pair of methacentric,1 pair of submetacentric, 2 pairs of subtelocentric and 17 pairs of telocentric and a pair of sex chromosome. X is a telocentric chro- mosome and Y is a metacentric. The C-banding pattern has been observed. The results Shows that C-bands are located at the cen- tromeres of each pair of chromosomes, and the short arm of Y chromosome is rich in heterochromatin.
