Duplicate genes created by a whole genome duplication start out with identical sets of regulatory sequence and are predicted to show identical patterns of gene expression. However, over time the expression pattern of the gene copes can diverge in different ways.
To compare the expression patterns of any homeologous gene pair in maize, download this spreadsheet and find the appropriate link.
