  # Title: Add support for homoeologues
  #
  # Description:
  #   To support homoeologues, we have to:
  #     - extend the "description" field of homology
  #     - add a new column in member_production_counts
  
  ALTER TABLE homology MODIFY COLUMN description ENUM('ortholog_one2one','ortholog_one2many','ortholog_many2many','within_species_paralog','other_paralog','gene_split','between_species_paralog','alt_allele','homoeolog_one2one','homoeolog_one2many','homoeolog_many2many');
  
  ALTER TABLE member_production_counts ADD COLUMN `homoeologues` int(10) unsigned default 0;
  
  # Patch identifier
  INSERT INTO meta (species_id, meta_key, meta_value)
    VALUES (NULL, 'patch', 'patch_75_76_c.sql|homoeologues');
