Physical map of Y chromosome sequence coverage and distribution of new informative SNPs. Schematic representation of Y chromosome including the pseudoautosomal (red) and heterochromatic regions (black) and enlarged view of the euchromatic portion of the MSY with different classes of euchromatic sequences: X-degenerate (yellow), X-transposed (pink), Ampliconic (blue), palindromes within Ampliconic classes (light blue), and Other (green). Redrawn from [7]. The lines indicates the distribution of Informative (green), Singleton (blue), and Discarded (red) SNPs along the molecule.
