摘要
以龟足的胚胎为材料,用空气干燥法制备染色体分裂相,并对染色体核型进行分析,结果显示:龟足的染色体数目为2n=32,核型为8m+6sm+2St.龟足染色体实际长度CL为0.85~2.47μm,染色体总长度为46.92μm.整个核型染色体长度依次减小,邻对染色体之间相差不明显,无异形性染色体出现。
The karyotype for Pollicipes mitella is studied with its embryos by means of hot-dropping method. The diploid chromosome number of Pollicipes misella is 2 n = 32 and the karyotype will be described by 8m+6sm+2st. The length of diploid metaphase chromosome(CL) is from 0.85 to 2.47 μm. The sex chromosome is not found.
