Hierarchical cluster analysis of differentially expressed genes between female and male embryos identified for the (a) Day 8, (b) Day 10, and (c) Day 12 embryos. Mean-centered expression values (log2 counts per million of sample – mean of log2 counts per million of all samples) for the female and male embryos are shown with significant differences in gene expression (FDR < 5%). Color scale is from − 2 (blue, lower than mean) to 2 (red, higher than mean). Each row represents one gene, each column represents one embryo
