Regions of the Y chromosome analyzed and distributions of variants discovered. (A) Y chromosome. (B) Location of the centromere. (C) Scale (bp) used in sections D through L. (D) Y chromosome unique regions. (Yellow bar) Segment of the reference sequence derived from haplogroup G (14,328,588–15,370,586); (blue bar) Haplogroup R1b regions. (E) Landmark sequence-tagged sites (STSs) used to define unique regions. (F) Bases in the chimpanzee reference sequence that can be aligned with the human reference (gray), or gaps in the alignment (orange). (G) Published variants lying within the unique regions. (H) Published variants variable within the 36 individuals. (I) Region sequenced at high coverage in the haplogroup A individual. (J) Depth of coverage of the region in track I. (K) All variable sites discovered in this study.
