translate English to French: The potential for gene flow may or may not have been high between wood and plains bison in historic times. It is unfortunate that most of the morphological and ecological studies, and all of the genetic studies, have occurred after the hybridization of wood and plains bison in the 1920s.
À l’époque historique, le potentiel de flux génétique entre le bison des bois et le bison des prairies peut aussi bien avoir été faible qu’élevé.
