Fig. 1From: Genetic effects of PDGFRB and MARCH1 identified in GWAS revealing strong associations with semen production traits in Chinese Holstein bullsLinkage disequilibrium analyses revealed three blocks for the identified SNPs in the PDE3A, MARCH1 and PDGFRB genes. The values in boxes are pairwise SNP correlations (D’), while bright red boxes without numbers indicate complete LD (D’ = 1). The blocks indicate haplotype blocks and the text above the horizontal numbers is the SNP namesBack to article page
