Figure 1.

Hierarchical clustering analysis comparing differentially expressed genes for “seminal plasma (SP) vs. BTS-embryos”. Rows and columns represent samples and genes, respectively. Colors correspond to the expression levels of the detected genes upregulated (red) and downregulated (green). Each vertical line represents single gene and each row represents single sample (SPS or BTS). Upper branches indicate relationships among different genes and left branches indicate differences among samples.
