  • a Sequences do not hit each other in a BLASTP search, but there is indirect BLASTP support for these ohnologs via a mutual homolog

  • b There is no direct syntenic support to suggest that these S. cerevisiae gene pairs are ohnologs, but a combination of some or all of the following convinces us they are ohnologs: synteny in the other post-WGD and pre-WGD genomes at that locus, two copies of the gene in other post-WGD genomes, correct clading in phylogenetic trees, or similar protein lengths
