Expression divergence of parental and homoeologous genes in the in silico parental mix and tetraploid A. tetraploideus. (A) Relative abundance of E homeolog transcripts. (B) Quantification of E-biased, I-biased and unbiased genes that were unique or shared between the parent mix and the tetraploid. (C) Heatmap of homeolog expression in the tetraploid relative to parental ortholog expression in the in silico parental mix for genes belonging to each of the four groups (I–IV). Each row represents a single gene
