  1. * All genes present in a paralogon, whether a duplicated copy is retained or not.
  2. † An ancestral gene is a gene present before a given duplication that could be represented by one or two retained paralogous copies.
  3. ‡ Percentage of genes from the annotated genome present in the ancestral blocks reconstructed from the paralogous relationships.
