  • ↵a Data for markers designated with asterisks were previously published (Collins-Schramm et al. 2003). MID numbers designate Marshfield insertion/deletions (http://research.marshfieldclinic.org/genetics), TSC numbers are as designated by The SNP Confortium (see http://snp.cshl.org/), and CV numbers are as designated by Applied Biosystems (https://myscience.appliedbiosystems.com/).

  • ↵b Genetic map positions based on Marshfield map positions. These were interpolated based on the sequence location of genetic markers on this map located within short physical distances flanking the physical location of the markers in the sequence assembly.

  • ↵c The approximate megabase position for each marker was determined by use of the Human Genome Browser (J. Kent, University of California, Santa Cruz, CA), based on the June 2002 human-genome draft assembly, http://genome.ucsc.edu/.

  • ↵d Allele frequencies for allele 1 (shorter polymorphism for diallelic indels, and α order of SNPs in forward direction).

  • ↵e The standard variance (also known as the Wahlund variance and shown as the f value or Fst) of each marker (see Methods).
