三江白猪与其他5个品种猪的群体遗传关系的分析Analysis on Genetic Relationship of Sanjiang White Pig and 5 Other Pig Breeds by PAPD
三江白猪 RAPD 亲缘关系
2008/1/8
摘要
应用100条RAPD引物对三江白猪及其杂交亲本长白猪和东北民猪，以及大约克夏、圣特西和法系大白猪进行亲缘关系的DNA多态分析。其中15条引物的扩增结果具有明显的多态，将其扩增结果进行聚类分析，发现三江白猪与长白猪（遗传距离d = 0.090）、与东北民猪（d = 0.175）的亲缘关系较近，与大约克夏(d = 0.263)、法系大白(d = 0.223)、圣特西猪(d = 0.580)的...
波尔山羊及其杂交改良后代群体遗传结构与亲缘关系研究 Studies of Genetic Structure and Genetic Relationship of Boer Goat and Its Upgrading Offspring to Tangshan Diary Goat
波尔山羊 杂交后代 遗传结构 亲缘关系 RAPD
2007/12/31
摘要利用RAPD标记和POPGENE、PHYLIP及SPSS等统计分析软件，研究了波尔山羊及其杂交改良后代群体的遗传结构及遗传亲缘关系。结果表明，波尔山羊与其杂交改良后代间特别是高代杂种间具有相似的多态基因座百分率、等位基因数和基因多样性。随着级进杂交改良代数的递增，高代杂种之间以及与改良亲本之间的群体遗传结构的差异逐渐缩小，群体间的基因分化降低，基因流动和遗传相似度增加，遗传距离缩小，高代杂种与...
