吉林白鹅类胰岛素生长因子Ⅱ的SNP及其与屠体性状的相关性分析
Study on IGF Ⅱ Gene SNP and its Effect on Meat Traits in Jilin White Goose
摘要
Abstract
Five primers were designed to amplify IGF Ⅱ gene and SNPs were detected by PCR-SSCP in 85 Jilin white goose meat stock population. The population genetic construction and the correlation between SNPs and carcass traits were analyzed.The results of PCR-SSCP showed that there were 3 genotypes of AA, AB, BB in exon 3 region of IGFⅡ , the genotypic frequency were 0. 7647, 0. 1412 and 0. 0941, respectively,AA was dominance genotypes. There were 2 allele genes of A,B, gene frequency were 0. 8353 and 0. 1647, respectively, A was dominance allele gene. One SNP was found in exon 3 region of IGF Ⅱ (A→G), sequence analogy indicated that it was a silent mutation, and the amino sequence was not change. By variance analysis for three genotypes, AA, AB genotypes were significant lower than BB genotype for half wipe chest weight and liver weight (P ＜0.05), AA genotype were significant lower than BB genotype for leg weight (P＜0.01). There were no significant level for whole wipe chest, chest weight and wing weight(P＞0.05).关键词
