| 摘 要： | 限制性片断长度多态性与家畜的生产性能存在相关,这种相关主要是由于限制性片断基因与数量性状位点存在连锁关系所引起。通过对与标记位点连锁的家畜近交系子二代数量性状分析,可获得数量性状位点的主效应和显性效应。同时,借助于限制性片断或已知片断的辅助选择,可使家畜的经济性状得到遗传改进。

| Abstract: | Restriction fragment length polymorphisms associate with the production performence of domestic animals which are mainlybecauce of the linkage between the restriction fragmant gene and the quantative trait locus. Based on the analysis of the quantative traits which link with marked loci in F-2 of a cross between two inbred lines, the main effect and dominnance effect of the quantative trait locus could be obtained. Meanwhile,wich the help of marker assisted selection or "known segment" selection, the economic trait of domestic animals could be improved. |
