Résumé : A total of 40 biochemical and four immunological markers found to be polymorphic in the rabbit in previous studies were screened in the AX/JU and IIIVO/JU inbred strains. Although the strains are considered unrelated, only eight (biochemical) markers were found to be polymorphic between the two strains. These eight markers were analyzed in an F 2 intercross population. Linkage was found for Est-5 and C on chromosome 1 and for Es-1, Est-2, Est-4, Est-6 and HP on linkage group VI. Two polymorphic markers, Es-3 and Mhr-1 could not be linked to any of the other markers.
