According to the results of analysis of genetic differentiation and Bayesian hierarchical cluster analysis of polymorphism in microsatellite loci, it was demonstrated that the development of marginal groups represented by subspecies level taxa (Greenland (Gadus macrocephalus ogac) and White Sea (Gadus morhua marisalbi) cod) occurred in the Late Holocene in a similar scenario, but in different regions and from different initial forms. The development of these reproductively independent cod groups was a result of physiological adaptations to arctic conditions in coastal northern water areas that developed under global cooling in the Subboreal.
