Effect of recombination on incongruences. Relationship between the triplet distance between individual gene trees and the two multigenic trees (supermatrix tree in A; BUCKy tree in B) as a function of the genetic distance between genes located on chromosome 3. The triplet distance between individual gene trees and the multigenic trees is the percentage of triplets of accessions that were resolved differently by a multigenic tree and a given gene tree. Solid line: best fit using all points; dashed line: best fit without a potential outlier (filled point). The genetic distance is connected to the chromosomal position according to the schematic diagram presented in C (red point: centromere; dark blue: centromeric regions; light blue: telomeric regions). D. Degree of incongruence among pairs of loci relative to the genetic distance on chromosome 3. Colors represent the degree of incongruence (white: no incongruence; red: strongest incongruence).
