Fig. 2From: An evaluation of the evolution of the gene structure of dystroglycanExpansion of the IG1-intron. a IG1-intron size as a function of genome size. b IG1-intron size as a function of DG gene size. The plots include data from 35 species representative of the metazoan phyla that encode DG. The fitted lines in the semi-logarithmic plots in panels a and b were obtained using a linear equation; the corresponding R2 value are 0.68 and 0.75, respectivelyBack to article page
