Gene flow and lack of population differentiation in Atlantic cod, Gadus morhua L., from Iceland, and comparison of cod from Norway and Newfoundland

Gene flow and lack of population differentiation in Atlantic cod, Gadus morhua L., from Iceland,... Restriction analysis of mitochondrial DNA was used to study genetic variation and geographic population structure of Atlantic cod from localities around Iceland. Gene phylogenies were constructed and geographic locations superimposed on these. The variation was not localized. Estimated gene flow was large. Thus, Atlantic cod in Iceland belong to a single genetic population. Analyses of published sequence variation of cod from Norway and Newfoundland showed that the extensive continuity of intraspecific phylogeny of cod in Iceland, which is very similar to other marine organisms with a similar life history, extends from Norway to Newfoundland and possibly to larger areas of the Atlantic. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Journal of Fish Biology Wiley

Abstract

Restriction analysis of mitochondrial DNA was used to study genetic variation and geographic population structure of Atlantic cod from localities around Iceland. Gene phylogenies were constructed and geographic locations superimposed on these. The variation was not localized. Estimated gene flow was large. Thus, Atlantic cod in Iceland belong to a single genetic population. Analyses of published sequence variation of cod from Norway and Newfoundland showed that the extensive continuity of intraspecific phylogeny of cod in Iceland, which is very similar to other marine organisms with a similar life history, extends from Norway to Newfoundland and possibly to larger areas of the Atlantic.
