  1. Because parts of the coding sequence are not available for the outgroup sequence from F. altissima, the 5’ and 3’ portions of F. ovina PgiC1 that were considered in the test span, respectively, coding sequence nucleotide positions 259-828 & 919-1530
  2. aThe number of fixed substitutions (per gene) between F. ovina and the outgroup (the number of nucleotide sites that are fixed for different nucleotides in F. ovina and the outgroup)
  3. bThe number of nucleotide polymorphic sites (per gene) within F. ovina
