Table 1 Comparison of radiation hybrid and genetic maps of wheat chromosome 3B

From: DNA repair and crossing over favor similar chromosome regions as discovered in radiation hybrid of Triticum

  1. Whole chromosome values are not averages for each category but re-calculated for the overall values. Values in the row are as of Saintenac et al. [7]. § Frequency of DNA breakage and repair per Mb and frequency of a crossing-over event per Mb. Resolution is the potential to uniquely resolve two markers at a distance equal or larger than this value. Chr: chromosome; BR freq: breakage and repair frequency; CO freq: crossing over frequency; cR: centiRays; Mb: megabase.
