Comparison with the physical and genetic maps of Trypanosoma brucei brucei. The genetic maps of T. b. brucei isolate TREU 927 and T. b. gambiense isolate STIB 386 are shown alongside the TREU 927 physical map of the same chromosome for (a) chromosome 1 and (b) chromosome 2. The average physical size of a recombination unit between each marker is given in kb/cM and the genetic distance given in cM. Dashed lines link the position of all markers on the physical map to their relative position on the genetic maps. Hot and cold spots are defined as threefold more or less recombination than average for each genetic map and indicated against the physical map by red and blue bars, respectively.
