^aMating type inheritance: A: karyonidal inheritance = mating type determined independently in each macronucleus; B: cytoplasmic inheritance = mating type reflects that of the cytoplasmic parent; C: synclonal inheritance = inheritance in accordance to Mendelian genetics (Miyake 1996; Phadke and Zufall 2009).
