Mitochondrial haplotype and microsatellite genotypes of killer whales in Iceland

This dataset includes mitochondrial haplotype (mtDNA) and 22 microsatellite genotypes from 61 killer whales (Orcinus orca) collected during dedicated fieldwork in Icelandic waters. 0 represents missing values. mtDNA sequences were visually inspected using the software FinchTV v1.4.0 and individual mtDNA haplotype was determined using the software BioEdit v7.2.5. Peak Scanner Software 2 was used to size each microsatellite allele.
