鸡的小卫星探针产生的猪DNA指纹图

DNA Fingerprints of Pigs Generated with a Chicken Minisatellite Probe

以一个鸡的小卫星ｃＭＳ１８为探针，对五指山小型猪、长白猪及枫泾猪进行了ＤＮＡ指纹分析。结果表明，五指山小型猪的相似系数（０７２１）显著高于长白猪（０５０３）和枫泾猪（０４８４），在遗传背景上也与后两者相距甚远。家系分析表明，鸡的小卫星探针产生的猪的ＤＮＡ指纹图的遗传符合孟德尔规律。

A chicken minisatellite probe cMS18 was used to generate DNA fingerprints of Wuzhishan micropig, Landrace pig and Fengjing pig. It was revealed that similarity coefficient of Wuzhishan micropig (0721) was much higher than both that of Landrace pig (0503) and of Fengjing pig (0.484). It was shown that Wuzhishan micropig was genetically distant to Landrace pig and Fengjing pig. Analysis of a porcine pedigree using cMS18 probe manifested that the segregation of DNA fingerprint bands was consistent with the Mendelian fashion.
