Note.— F = Female genomes; M = Male genomes; RM* = These genomes are recently-masculinized genomes (see text for details).
a
These complete M. trossulus mtDNAs correspond to or have high affinity with the corresponding ancestral M. trossulus genomes from North America [30], [97].
b
DNA divergences based on partial cox1 sequences [42]. Sequence divergences are given in percentages nucleotide difference for the total number of aligned nucleotides.
