Close genetic similarity of Atlantic and Pacific skipjack tuna (Katsuwonus pekamis) demonstrated by restriction endonuclease analysis of mitochondrial DNA

Abstract Restriction endonuclease analysis of mitochondrial DNA indicated a surprisingly high degree of genetic similarity between skipjack tuna (KarsuLcorzus pe/urni.r) from the Atlantic and Pacific Oceans.

Description
Summary:Abstract Restriction endonuclease analysis of mitochondrial DNA indicated a surprisingly high degree of genetic similarity between skipjack tuna (KarsuLcorzus pe/urni.r) from the Atlantic and Pacific Oceans. The present results (1983) support the findings of previous morphological and electrophoretic studies. Evidently. since the uplift of the Panama land bridge about 3.1 million years ago, there has been continued genetic contact between Atlantic and Pacific skipjack tuna, presumably via the Southern Ocean.
