Efficiency of Genotyping by Sequencing in inferring genomic relatedness and molecular insights into fat tail selection in Tunisian sheep

A case-control design GWAS was performed to detect significant variants associated to sheep tail shape in Tunisian sheep using two different tail types (short fat tailed vs. long thin tailed). A general linear model analysis (GLM) implemented in TASSEL 5.0 (Glaubitz et al. 2014). Phenotypic data: We used GBS data of 148 Tunisian sheep samples. The short fat-tailed sheep was represented by Barbarine breed were coded as cases and 63 long thin-tailed sheep as controls. Genotypic data: Attached the filtered GBS genotypes of 91,106 SNPs in 148 samples converted to plink format (ped and map files).
