  1. *The nucleotides marked as 'N' were not included in the analysis. Only 30 chromosomes were used in the analysis because chromosomes 29-31 and 33-38 were too small to assemble [39]. The microchromosomes included chromosomes GGA11-28, 32 and W and the macrochromosomes included chromosomes GGA1-5 and Z.
