Distribution of recombination events among regions of different SNP densities. Recombination events in the recombinant clones show a negative correlation with SNP densities. (A) COs found in our study. (B) COs identified by VNTR typing and reported by Katzer F. et al. . (C) NCOs found in our study. MM_SNP: SNP typing of MugugaMarikebuni. MU_SNP: SNP typing of MugugaUganda. MM_VNTR: VNTR typing results of MugugaMarikebuni.
