↵a N refers to A, C, or T in the trinucleotide. CGG is included in the CG dinucleotide count. The trinucleotides (C and two downstream nucleotides) from the mtDNA and ptDNA corresponding to T mutations in the trinucleotides of the numtDNA and nuptDNA were used in the analysis. In the case of the organelle G nucleotide to the nuclear A substitution, the C and its two downstream nucleotides in its complementary strand of the mtDNA and ptDNA were used in the analysis.
