Patterns of gene expression in allopolyploids and their diploid parents. In the upper row, example levels of gene expression for three homologous genes in two diploids are shown. The lower row shows six example patterns of gene expression in an allotetraploid formed from the two diploids, with the contribution of the two homoeologs shown in red and blue: (1) additive patterns of gene expression, (2) expression-level dominance by the A sub-genome at all loci, with equal expression of homeologs at each locus, (3) expression-level dominance by the B sub-genome at all loci, with additive expression of homeologs at each locus, (4) expression-level dominance by the B sub-genome at all loci, with homoeologous expression bias in favour of the B sub-genome, (5) expression-level dominance by different sub-genomes at different loci, and homoeologous expression bias in favour of the A sub-genome at all loci, (6) no expression-level dominance, and homeologous expression bias differing among loci.
