Genes identified based on the wMI for N’Dama breed. a The correlation network of 30 genes selected using the wMI of SNP types between N’Dama and Ogaden breeds. Circles denote genes including SNPs identified by the wMI and dark grey octagons represent the genes annotated in the result of GO analysis. Dark red edges indicate strong positive correlations and dark green edges show strong negative correlations (gene pairs with a correlation coefficient value larger than 0.45 or smaller than -0.25 are connected). b GO analysis on the extracted genes by adjusting thresholds from the constructed correlation network. A vertical line indicates an FDR-adjusted p-value (0.05). c The genotype profiles of the identified genes including ACCN1, CTNNA2, FHIT, and USH2A are shown. The SNP positions of each gene reveal clearly different patterns between N’Dama and Ogaden breeds. Each logo indicates A (A/A), T (T/T), G (G/G), C (C/C), L (A/T), D (A/G), E (A/C), F (G/T), H (C/T), and I (C/G). Upper table shows the types of SNP alleles for each breed. Values in the parentheses represent the numbers of samples with each allele for four genes
