Data from: Geographic extent of introgression in Sebastes mentella and its effect on genetic population structure
Genetic population structure is often used to identify management units in exploited species, but the extent of genetic differentiation may be inflated by geographic variation in the level of hybridization between species. We identify the genetic population structure of Sebastes mentella and investi...

Genetic population structure is often used to identify management units in exploited species, but the extent of genetic differentiation may be inflated by geographic variation in the level of hybridization between species.

The data support an historical divergence between the “shallow” and “deep” groups, beyond the Irminger Sea where they were described previously.
