  • Locations of centromeres on genetic map?

    Is there a handy table showing the approximate positions of the centromeres on the genetic map, with units of Mb and also cM? Even better if it also shows the approximate boundaries of standard cytological segments (the segments identified by names such as p11, q3, etc.).

    Update: The Wikipedia article "Centromere" has a table showing human centromere locations and total lengths in Mb, but no specific source was cited. This information is enough to provide a good idea of which matching segments from GEDmatch or FTDNA include the centromere. If anyone can pin down the source of the table and/or provide a table that also shows the centromere locations along the genetic map in cM units, please let me know!

      Not sure if this will help

      For Build 37
      http://genome.ucsc.edu/cgi-bin/hgTables

      select following

      Clade > Mammal
      Genome > Human
      Assembly > Feb 2009 (GRCh37/hg19)
      Group > All Tables
      Database Hg19
      Table > Gap
      Region > Genome

      Then select > Get Output

      For build 36

      same as build 37 but select following
      Assembly > Mar 2006 (NCBI36/hg18)

        There is a downloadable table from the UCSC Genome Browser. This is for Build 37.

        Substitute hg18 for hg19 if you want to see positions for Build 36 (FTDNA and GEDmatch).
