Table II. Tissue expression pattern divergence between pairs of duplicates for type I and type III genes.
Expression pattern (expressed or not in each tissue) between duplicated gene pairs is compared between type I and type III WGD retained genes. Similar, Both gene copies express in most of the tissues; asymmetric, one gene expresses in most of the tissues, while the other copy does not express or is expressed in very few tissues.
