Fig. 1From: Genetic diversity, evolution and selection in the major histocompatibility complex DRB and DQB loci in the family EquidaeThe horse MHC DR and DQ loci studied. Expressed DR and DQ genes located on ECA20 of EquCab3.0 are represented as solid-line arrows, pseudogenes as dashed-line arrows. Transcriptional directionality is indicated by arrows. Genes analyzed in this study are in bold. Based on Viluma et al. [24]Back to article page
