Figure 2From: Dating and functional characterization of duplicated genes in the apple (Malus domestica Borkh.) by analyzing EST dataSize distribution of apple gene families. Distribution of gene family sizes in the apple estimated by single-linkage clustering of BLASTP sequence similarity searches. Gray line: best fit of the distribution to a power-law with the equation f(x) = 4363x-2.35 (R2= 0.97).Back to article page
