Recombination parameters used for the B. rapa female recombination map. Parameters are: the genetic lengths, in centiMorgan, the proportion p of interfering crossovers and the shape parameter, nu, of the gamma distribution used to draw the inter-crossover distances under interference. These parameters are defined for a normal recombination rate (wild type, WT) and for increased recombination, either under Boost or HR. The values of p and nu are from [18] for WT and Boost but for HR we assumed no interference (p = 0, nu = 1).The genetic lengths under HR were set to the values measured under Boost
