摘要
Abstract
The whole genomic association analysis (GWAS) of lambing traits of Duolang sheep was conducted by using the whole genomic resequencing technique, and the candidate genes and molecular markers related to the breeding traits of sheep were excavated.The Fst test screened out 135 significant windows, and their Fst value was mostly concentrated within 0.35~0.50.A total of 51 genes were obtained by the gene annotation to the selected significant windows.The further enrichment analysis found that the maximum value of Fst was 0.8710, and it was located within the gene NCOA1.In the female gametogenic clauses, the common gene of polyembryonic group and unigerminal group was INHBA.Through using ENSEMBLE database for gene annotation, a total of 28 genes (such as ACP1, ING5, ARNT, etc.) had intersection with the significant window.The disclosure of these candidate genes and molecular markers has reference value and theoretical significance for the excavation of functional genes related to sheep reproductive traits.关键词
