Abbreviations: a, adductor muscle; avg, average; b, body; F, F mtDNA ratio in female samples; Fm, F mtDNA ratio in male samples; M, M mtDNA ratio in male samples; m, mantle; MAD, median absolute deviation; mdn, median; NA, calculation not possible; s.d., standard deviation; w, whole animal; ♀, number of female samples; ♂, number of male samples.

Statistics were calculated on all suitable technical replicates available for each sample. Three replicates were used for each sample (except for a female adductor, where two were used; Supplementary Table 2). No M mtDNA was detected in class 2 adductors and mantles.
