aSNVs are the positions where neither QM6a nor CBS999.97(MAT1-1) is null.
bInDels are the positions where only QM6a or CBS999.97(MAT1-1) is null.
cFor the 1n:3, 2n:2, 3n:1 and 4n:0 markers, neither QM6a nor CBS999.97(MAT1-1) is null. Moreover, 1n, 2n, 3n and 4n represents the numbers of F1 progeny with a null at the corresponding position, respectively.
dRIP involves C:G-to-T:A transitional mutation in duplicated DNA. RIP (Q) and RIP (C) are QM6a-specific and CBS999.97(MAT1-1)-specific RIP, respectively.
eIM-1 is the position where ≥1 F1 progeny harbors an authentic nucleotide that is different from the two corresponding nucleotides in QM6a and CBS999.97(MAT1-1), respectively. RIP is excluded.
fIM-2 are positions where either QM6a and CBS999.97(MAT1-1) is null, but the corresponding positions contain an authentic nucleotide in ≥3 F1 progeny.
gIM-3 are positions where both QM6a and CBS999.97(MAT1-1) are nulls, but the corresponding positions contain an authentic nucleotide in ≥1 F1 progeny.
