Fixed differences between killer whale types and oceanic regions

[i] Two haplotypes with large sequence gaps (ENASU and AntC7) were not included in calculations.
[ii] aOffshores include unknown ecotype sample from western Atlantic, Newfoundland (WNAUCAN), and unknown type samples from Mexico and Clipperton Island.
[iii] bAll Antarctic A except sample AntA2, which clusters with the North Pacific Transients (see text).
[iv] cAll Antarctic except sample AntA2, compared with all other complete haplotypes.
[v] dAll samples in Transient clade (not including AntA2), compared with all other complete haplotypes.
