A)Homolog and homoeolog relationships among Gossypium A- and D-genome diploids and allotetraploids.B, C, and D) Pairwise plots of dN/dS ratios for between the A- and D-genomes of the allotetraploids G. barbadense and G. hirsutum, and the A- and D-genome diploids G. arboreum and G. raimondii. Axis are plotted on a natural log scale, with R2 values listed in the upper-left corner. Each dot represents one contig and the red line indicates the slope of a theoretical 1:1 relationship.
