Graphical representation of haplotype block H02 located on BTA 1. The allelic variants of H02 are presented as the combination of the five SNPs that form this haplotype. The nitrogenous bases in red represent the possible alleles for each SNP whereas those in black are the conserved sequence flanking the SNP. The five alleles for H02 are: CCCCG, CCCTG, CTCCG, CTACA, and TCCCG. The position of the SNPs, and the number and length of exons and introns within genes were obtained in NCBI according to the Bos_taurus_UMD_3.1 assembly.
