Classification of M74 groups and stages by gene expression. For the explanation of sample groups, see Table I. Euclidian distances between log₂(ER) values were clustered using Ward's method. H denotes healthy fry 50 vs 180 ATU and M denotes M74 (I1 and I2) 50 vs 180 ATU hybridizations. The other hybridizations are M74 vs healthy fry of the same age.
