(a) Overview of oggmap steps. (b) Orthomap for the query species zebrafish (Danio rerio). Each gene (seqID) from an Orthogroup is assigned to a gene age class (PSnum, PSname) given a continuity score (PScontinuity). (c) Number of genes per gene age class. (d) Boxplot of zebrafish (D.rerio) TEI values grouped per embryo stage. (e) Contribution of gene age classes to the global TEI per embryo time (nematode). Zebrafish scRNA data UMAP, each cell is colored by embryo stage (f) or its corresponding TEI value (g).
