a
Number of individuals tested.
b
Indicates whether all individuals within species were homoplasmic for guanine (G) or heteroplasmic for guanine and adenine (G/A) at mitochondrial genome position 11973.
c
Assay used to ascertain 11973 heteroplasmic status: direct sequencing with forward (F) or reverse (R) primer, and HpyCH4V digestion (D).
d
Primer pairs used to amplify the 11973 mitochondrial genome region by PCR: VF1 (5′-CCCGTTTGAGTGTGGGTTTGA), VF2 (5′- TGGTTTTTGATGTTGAGATT), 2138ND (5′-TCCTAGGGATTGGCCATTTA), VR2 (5′- CGCTTACGTTACGATAAACT) and 1737ND (5′- TATTTGGGTGCGAGGAACTC).
