Fig 3. Meiotic recombination event counts and spatial regulation in the absence of Mec1 or Rad24.

A) The average number of non-exchange chromosomes per octad/tetrad, plotted against the average number of crossovers. Dotted line represents random simulation (see Methods). B) The number of non-exchange chromosomes against the number of crossovers in each meiosis studied. The shaded area represents the area in which 90% of the simulations fell (smoothed). C) The relationship between the length of a chromosome and the number of times it was a non-exchange chromosome in 27 mec1-mn and rad24Δ mutant meiosis. D,E) The relationship between the recombination event count and the CO/NCO ratio in each cell. The plotted lines are linear models of all MSH2 (D) or msh2Δ (E) strains.
