Signatures of selective sweep at the N’Dama HCRTR1, SLC40A1, EPB42, and STOM gene regions. Nucleotide diversity plots of the HCRTR1 (a) and SLC40A1 (c) genomic regions. Haplotype diversity at the HCRTR1 (b) and SLC40A1 (d) gene regions (gray area). The major allele at each SNP position in N’Dama is colored in red, the minor one in white. The star (*) denotes non-synonymous N’Dama SNP identified at the HCRTR1 gene region. e Frequency of N’Dama fixed haplotype (SLC40A1 region) in others breeds with comparison with major observed haplotype(s) (frequency > 0.15 shown). Nucleotide with green background represents distinct polymorphism compared to the major SNP allele present in N’Dama. f, g Structure of the EPB42 and STOM gene with exons indicated by vertical bars. Non-synonymous SNPs represent p.Arg503His and p.Met48Val and are highlighted in yellow. Different color represents different alleles, and frequency of each haplotype is indicated on the right side of the figure
