Gene Coexpression and Evolutionary Conservation Analysis of the Human Preimplantation Embryos

Figure 5

Distributions of different gene ortholog types comparing human with zebra fish: (a) one-to-many ortholog, (b) one-to-one ortholog, and (c) new genes. For each stage, the vertical axis shows the observed proportions minus expected proportions of genes in each ortholog type. The asterisks denote significant enrichment () in a specific ortholog scenario for each stage.
