Genome-wide selection signals in fat-tailed and thin-tailed sheep. (A) Geographical distribution of sampling for whole genome and transcriptome sequencing. A total of 663 fat-tailed sheep and 248 thin-tailed sheep whole genome data were collected, and transcriptome data of 13 fat-tailed sheep and 47 thin-tailed sheep were collected. (B) Whole-genome selective signals between fat-tailed sheep and thin-tailed sheep based on the pairwise F_ST selection test. (C) Whole-genome candidate selective regions between fat-tailed sheep and thin-tailed sheep by the log₂(π ratio) selection test. (D) Genome-wide selective signals between fat-tailed sheep and thin-tailed sheep by the XP-CLR test. The horizontal red dashed line corresponds to the genome-wide significance threshold (top 5%: F_ST = 0.1608, log₂(π ratio) = 0.5215, and XP-CLR = 0.8870). (E) The upset plot shows the number of genes and their intersection obtained from the three genome-wide selection signal analyses when the significance threshold is top 5%
