Genetic analyses of the archaeological Atlantic cod specimens from Oslo. (a) Geographical distribution of modern inversion frequencies of chromosomal inversions in Atlantic cod (LG1, LG2, LG7 and LG12) from reference populations across the North Atlantic Ocean. The map is modified from Martínez-García et al. [8]. Alleles associated with a northernmost (Northeast Arctic and Iceland) composite genotype distribution are assigned in orange. Alleles associated with a north-central (Norwegian Coast, the North Sea, the Irish Sea, Øresund) genotype distribution are assigned in grey. Oslo’s archaeological sites are indicated with a red square. (b) Genomic assignments to a geographical area, a source population and a genotypic group are based on the frequencies of chromosomal inversions of Atlantic cod (LG1, LG2, LG7 and LG12) as per Star et al. [5]. Percentages (%) indicate the highest probability of being from one population and area.
