摘要
通过对约克夏(4头)、互助猪(4头)和约克夏×互助猪杂交一代(40头)外周淋巴细胞的培养、制片、Bloom法银染和光镜下分析,结果表明猪Ag-NORs在品种间、同一品种不同个体间、同一个体不同细胞间和同一细胞不同染色体间均有多态性。且约克夏猪的Ag-NORs众数为2,互助猪Ag-NORs众数为3,其杂一代介于亲本之间;并且纯种猪的Ag-NORs相对稳定,杂种猪变化较大。
This study was conducted to investigate the polymorph i sm in Yorkshire (4), Huzhu (4) and the first filial generation (40) by sampling, culturing and Bloomsilver staining the peripheral lymphocyte. The result by microscopic examination shows polymorp hism was observed between specieses, individuals in the same species, cells in t he same body and chromosomes in the same cell. The mode in Yorkshire is 2, in Hu zhu is 3 and in the first filial generat ion is among their parents. The Ag-NORs in pure breed is stable relatively, while changeable in mixed breed.\;
