Fig. 4From: Conversion between duplicated genes generated by polyploidization contributes to the divergence of poplar and willowThe correlation between conversion and the density of duplicated genes on selected chromosomes. a-d The correlation patterns of chromosomes 7 and 12 in P. trichocarpa and chromosomes 11 and 15 in S. brachista. The Y-axis indicates the density of duplicated genes (blue lines) and conversion rate (green lines) for selected chromosomes in P. trichocarpa and S. brachista. The X-axis indicates the distance of the duplicated or converted genes from the chromosome termini. (PDF 503 kb)Back to article page
