From: X chromosome variants are associated with male fertility traits in two bovine populations
Association results on the X chromosome of Brahman (left) and Tropical Composite bulls (right). Each coloured region represents a QTL, defined by at least five SNPs associated (P < 10−8) with each phenotype. Phenotype abbreviations are provided next to each QTL (phenotypes and abbreviations, as described in Table 1). The X chromosome harboured QTL in both breeds; some QTL overlap. The pseudo-autosomal region boundary (PAB) is marked on the chromosome to show that all reported QTL were localized before the boundary, in the non-autosomal region
