Extended Data Fig. 9

a, Counts of gene families containing the specified number of retained paralogues in gar, lamprey (P. marinus) and hagfish (E. atami). b, Comparison of the tissue-specificity of gene expression (tau index) for ohnologue gene families in lampreys, hagfish, gar and the (unduplicated) amphioxus outgroup (Methods). The distribution of the maximal tau value for each gene family is shown. c, Node-specific gene loss events inferred by GeneRax in a species–gene tree reconciliation framework (Methods). Species labels are specified in Supplementary Table 8. d, Loss of Panther families across deuterostomes species inferred as the most parsimonious events from gene-family composition. e, Genome structure of the two clusters of expanded keratin genes, with mRNA expression in slime gland and skin (blue track).
