The effect of sequence polymorphisms on recombination is not fully understood. Here, the authors develop the seed-typing method to map crossovers (COs) by sequencing and show that COs occur preferentially within polymorphic hotspots and that this effect depends on the mismatch repair gene MSH2 in Arabidopsis.
