| 摘 要： | 克隆了大白、长白和梅山猪肌球蛋白轻链调控蛋白2基因(MRLC2)内含子2序列,经比对发现,在内含子2中18个碱基突变和8个碱基缺失,其中179bp处的C/T突变引起Hin6I酶切位点的改变,运用PCR-Hin6I-RFLP对179头大白×梅山F2代猪进行家系关联分析,结果表明该酶切位点与屠宰率呈极显著相关,表现为加性效应,CC基因型个体比CT基因型、TT基因型个体有更高的屠宰率;与大理石纹评分呈显著相关,CC基因型个体评分比CT基因型、TT基因型个体高。 |
| 关 键 词： | 猪 肌球蛋白轻链调控蛋白2基因 多态性 关联分析 |

| Abstract: | In this study,we obtained the sequence of intron 2 of the porcine MRLC2 gene from Yorkshire,Landrace and Meishan pig.Eighteen SNPs and 8 bases deficiency were detected by sequence analysis.The single nucleotide polymorphism(SNP) of C179T in intron 2 was significantly associated with dressing percentage.The SNP showed significantly additive effect.Individuals of the CC genotype had significantly higher dressing percentage than those of TT and CT genotype.CC genotype had significantly higher meat marbling tha... |
| Keywords: | pig MRLC2 gene polymorphisms correlation analysis |
