Fig. 6: Selection signatures and haplotype patterns of the high-altitude adaptation, small body size, and large ear size-related genes.
A The top diagram represents the selection signatures detected using the LSBL and θπ methods in the high-altitude adaptation-related gene, THSD7A. The bottom diagram shows the gene structure of the THSD7A gene. The red rectangle indicates the identified region under selection. B Haplotype patterns in regions under selection for THSD7A. Each row represents a phased haplotype, and each column represents a polymorphic SNP variant. The reference and alternative alleles are indicated in cream and red colors, respectively. C Phenotypic variations for ear size, represented by Dapulian (top) and Lantang (bottom) pigs. Images were sourced from the Animal Genetic Resources in China: pigs. D The top diagram represents the selection signatures detected using the LSBL and θπ methods in the large ear size-related gene, MSRB3. The bottom diagram represents the gene structure of MSRB3. The red rectangle represents the identified region under selection. E Haplotype patterns in regions in MSRB3 that are under selection. Each row represents a phased haplotype, and each column represents a polymorphic SNP variant. The reference and alternative alleles are indicated in cream and red colors, respectively. F The top diagram represents the selection signatures detected by LSBL and θπ methods in the small body size-related gene, RBFOX1. The bottom diagram shows the gene structure of RBFOX1. The red rectangle indicates the region under selection.
