  • 简介:织物表示和石头的isozymes的股票变化挣扎(Kareiusbicoloratus)与水平淀粉胶化电气泳动被分析。为十四酶assayed,31loci被记录。结果显示检验的所有isozymes是obviouslytissue特定的。SOD~的表情*,GDH~*,G3PDH-2~*并且ADH-2~*仅仅在肝被检测,SDH-1~*,MDH-1~*并且ADH-1~*仅仅在肌肉,和LDH-B~*并且LDH-C~*仅仅在眼睛。在比较,MDH-2~*,GPI-3~*并且SDH-2~*在检验的所有纸巾被检测。检验的另外的loci在许多纸巾被检测。肌肉和肝被选择检测Qingdao和Weihai的二张地理股票的isozyme变化,山东省,中国。多态的loci(P_(0.99))的百分比是29.17%和25.00%,观察杂合现象(H_0)were0.028±0.014和0.040±0.019,和期望的杂合现象(他)分别地是在Qingdao和Weihai存货的0.039±0.017and0.052±0.022。分别地,基因区别(F_(st))和在二张股票之间的基因距离(D)的系数是0.012和0.0011显示基因区别在他们之间是低的。与另外的种类ofPleuronectiformes相比,多态的loci的百分比和K.bicoloratus的吝啬的杂合现象在中间的水平。
