Table 2. Variation in heteroplasmy levels between measurements at each developmental stage of randomly chosen oocyte and offspring samples and of all females to determine the measurement error.

	n	N	Mean SE
Mother	10 to 13	5	0.50
Oocyte	3	31	0.88
Offspring	3	18	0.58

n: number of repeat measurements per sample, N: total number of individuals from which repeat measurements were taken, mean SE: mean standard error across all individuals.
