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.

Gene Pair Expression Patterns

Even Correlation

A duplicate pair of homeologous genes from maize which diverged 12 million years ago. Both genes show near identical patterns of gene expression, as well as near identical levels of expression in all tissues examined

Unbalanced Correlation

A duplicate pair of homeologous genes from maize which diverged 12 million years ago. Both genes show near identical patterns of gene expression, however GRMZM2G092085 produces only half as much RNA as GRMZM2G029186
