From: A single polyploidization event at the origin of the tetraploid genome of Coffea arabica is responsible for the extremely low genetic variation in wild and cultivated germplasm

Figure 1

Homoeologous replacement on chromosome 7. The brown rectangle indicates a large event of homoeologous replacement. The upper plot indicates the fractions of nucleotides in 100-kb non-overlapping windows classified as gene space (yellow), repetitive DNA (red), and intergenic low-copy DNA (white background). The lower plots illustrate the average read coverage in 2-kb non-overlapping windows (red dots) and a cubic smoothing spline of the data (black line), the alignment of C. arabica scaffolds, sorted by their subgenome assignment (canephora in green, eugenioides in blue) against the genome reference of the diploid C. canephora.
