  • a From http://www.agron.missouri.edu/cMapDB/cMap.html (March 2003).

  • b Genetic map is the classical genetic map, compiled by Ed Coe from cooperators.

  • c IBM is an intermated B73/Mo17 recombinant inbred high-resolution molecular map.

  • d The average number of RNs × 50 cM/RN.

  • e Centimorgans divided by 50.

  • f This molecular map includes recombination events from three meioses (K. Cone, personal communication), so the centimorgans presented on the web site have been divided by 3 here for the purpose of comparison using the standard definition of centimorgans (Tamarin 2002).
