【摘要】 根据山羊2号和8号染色体遗传连锁图谱,选取8个微卫星标记INRA040、LSCV22、LSCV37I、DVGA64、FCB011I、NRA129、SRCRSP10和CSSM47,分析它们与波尔山羊产羔性状的关联。结果表明:所研究的8个波尔山羊微卫星基因座均为高度多态性基因座(PIC>0.5)。与波尔山羊产羔性状有显著效应的等位基因10个。其中与波尔山羊第1胎产羔数有显著正效应的等位基因1个:LSCV22的189 bp;与波尔山羊第1胎产羔数有显著负效应的等位基因4个:LSCV22的179和191 bp,SRCRSP10的273和303 bp;与波尔山羊第2胎产羔数有显著正效应的等位基因6个:LSCV22的189 bp、IDVGA64的281、283和245 bp、FCB011的143和165 bp。更多还原

【Abstract】 According to the goat genetic linkage map of chromosome 2 and 8,eight microsatellite markers(INRA040,LSCV22,LSCV37,IDVGA64,FCB011,INRA129,SRCRSP10 and CSSM47) were chosen to analyze their correlation with the litter size of Boer goat.All the eight microsatellite loci in Boer goat were high polymorphism locus(PIC > 0.5).Ten alleles were found to be significantly correlated with litter size of Boer goat.189 bp of LSCV22 weas positively correlated to first parity litter size of Boer goat.179 and 191 bp of LSCV22,273 and 303 bp of SRCRSP10 had negative correlation with first parity litter size.189 bp of LSCV22,281,283 and 245 bp of IDVGA64,143 and 165 bp of FCB011 were positively correlated to second parity litter size.更多还原
