【摘要】 应用寡苷酸探针 (CA/GATA/TCC) 5 检测安哥拉山羊和安哥拉山羊级进杂交F2 、F3 的DNA指纹图谱 .结果表明 ,供试羊只个体平均检出 1 8.2± 0 .4条谱带 ;在安哥拉山羊、F2 、F3中 ,探针的鉴别机率分别为 1 .38× 1 0 -12 ,1 .1 8× 1 0 -13 ,0 .5 0× 1 0 -10 ;群体内DNA指纹平均相似系数安哥拉山羊F2 、F3 分别为 0 .45 39,0 .40 77和 0 .6 1 1 1 ;在安哥拉山羊DNA指纹图谱中 ,发现 2 .3Kb和 8.6Kb谱带为特异性谱带 .更多还原

【Abstract】 DNA fingerprints of Angora goats and their upgrading F 2,F 3 were established by oligonucleotide (CA/GATA/TCC) 5. The results are as follows: (1) The average number of bands are 18.2±0.4 per individual; (2) The resolution in Angora goat, F 2,F 3 is 1.38×10 -12 , 1.18×10 -13 ,and 0.50×10 -10 respectively; (3) The mean band similarity coefficient is 0.4539 in Angora goats, 0.4077 in F 2, and 0.6111 in F 3; (4) The 2.3kb band and the 8.6kb band are believed to be the specific bands of Angora goat.更多还原
