摘要:

为了解波纹唇鱼（Cheilinus undulates）的细胞生物学特征，采用植物血凝集素PHA、秋水仙素腹腔注射和空气干燥制片法以头肾组织为材料，对波纹唇鱼的染色体核型进行了研究。结果表明，波纹唇鱼具有染色体48条，核型公式为2n=48=6m+42t，NF=54，未发现随体、次溢痕及性染色体，其核型符合典型的高位类群鱼类核型特征。

The karyotype of Cheilinus undulates

Abstract:

To explore the cell biological characters of Cheilinus undulates, we analyzed the karyotype of C. undulates from their renal tissues by the PHA and colchicine injection-air drying method.The results showed that there were 48 chromosomes in C. undulates and its karyotype formula was 2n=48=6m+42t, NF=54. Satellite chromosome, secondary constrictions and sex chromosome were not found in C. undulates. The karyotype of C, undulates is in accordance with the higher group of fish evolutionary taxonomy.

Key words: Cheilinus undulates chromosome karyotype
