NA: not assessed, C: control crosses (M. edulis x M. edulis for the production of pure-species diploids), H: hybrid crosses [(M. edulis x M. trossulus or M. edulis x (M. edulis x M. trossulus hybrid)], T: triploid crosses (M. edulis x M. edulis, from which a batch of eggs was used to produce triploids), Fed-1: the COIII mtDNA digestion pattern typical of the maternal M. edulis genome, Med-1: the COIII mtDNA digestion pattern typical of the paternal M. edulis genome, Mtr-1: the COIII mtDNA digestion product typical of the M. trossulus paternal genome.
