Hierarchical clustering and expression profile of differentially expressed genes Hierarchical clustering and expression profile of genes presented in Table 2. The day of gestation is indicated at top. Accession numbers and gene symbols are presented. For each gene individually, each value was normalized by division with the root mean square calculated from the six values. As a consequence, the relative values obtained for one gene cannot be compared to those of other genes. Expression levels are presented from black (no expression) to yellow (high relative expression level). The clustering was generated using the Genesis 1.6.0 Beta1 software (agglomeration rule of average linkage and Euclidean measurement distance) [26]. M, male; F, female.
