| 摘要: |
| 采用家猪外周血淋巴细胞培养法，以FdU作诱导剂，对关中黑猪染色体脆性位点进行了研究，结果表明，FdU型脆性位点主要发生于1p,1q,2q,4q,6q,13q,15q,16q染色体，其中1p21,1q31,1q32,2q21,4q21,6q21,13q11,13q33,13q41,14q21,15q24,16q14,16q21等为脆性位点高发区，最后对脆性位点的分类进行了简要讨论。 |

| Abstract: |
| By using the peripheral blood lymphocyte culture method,a study on fragile sites in Guanzhong black pig chromosomes was done with Fluorodeoxyuridine (FdU) as inducer.The FdUsensitive fragile sites were indentified on chromosomes 1p,1q,2q 4q,6q,13q,14q,15q,16q in the main,especially the chromosomes 1p21,1q31,1q32,2q21,4q21,6q21,13q21,13q33,13q41,14q21,15q24,16ql4,16q21 were usually high frequency region of fragile sites. The classification of fragile sites was also briefly discussed. |
