  1. a Expressed as a percent of the whole genome and the total number of base pairs.
  2. b Includes all unassigned sequences ≥ 10 bp in length.
  3. c The location and size of the UR is defined by upstream and downstream neighbouring genes.
  4. d Data for Dendropoma maximum and Thylacodes squamigerus include pseudogene sequences found within some unassigned regions (see Tables 2 and 5).
