Divergence times of cenhaps. (A) Divergence times between NAM lines and B73 over pericentromeric regions. Dots represent estimated divergence times over 20-kb windows. The cenhap regions are highlighted in blue. (B) Cenhaps outlined in A. The divergence times over CentC regions (orange bars) are not reliable because of inaccurate alignment over CentC arrays and embedded retrotransposons within the arrays.
