Genes identified based on the MI and XP-CLR for N’Dama breed. a The correlation network of 131 genes selected using the MI and XP-CLR of SNP types between N’Dama and Ogaden breeds is presented. Circles denote genes identified by the intersection of MI and XP-CLR 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 are strong negative correlations (gene pairs with a correlation coefficient value larger than 0.9 or smaller than -0.4 are connected). b GO analysis on the extracted genes by adjusting thresholds from the constructed correlation network is shown in this figure. A vertical line is an FDR-adjusted p-value (0.05). c The genotype profiles of the identified genes, CALCR, FGF23 and CDK6, for 10 representative SNP positions of each gene clearly show different patterns between N’Dama and Ogaden breeds. Upper table reveals the types of SNP alleles for each breed. Values in the parentheses denote for the numbers of samples with each allele for the three genes
