Data from: Colonizing the wild west: low diversity of complete mitochondrial genomes in western North Pacific killer whales suggests a founder effect
In the North Pacific, fish-eating R-type “resident” and mammal-eating T-type “transient” killer whales do not interbreed and differ in ecology and behavior. Full-length mitochondrial genomes (about 16.4 kbp) were sequenced and assembled for 12 R-type and 14 T-type killer whale samples from different...
