Copy-number variation on Yp. Schematic view of copy-number variable regions of the Y chromosome short arm (Yp) superposed on SNV-based phylogenetic tree. All CNVs shown overlap a segmental duplication in the reference sequence (strain C57BL/6 J). One CNV overlaps a known protein-coding gene: an expansion of the ampliconic Rbmy cluster (green) in M. m. musculus. Color scheme for Mus taxa follows figure 2.
