ZOO-FISH ANALYSIS - THE AMERICAN MINK (MUSTELA-VISON) CLOSELY RESEMBLES THE CAT KARYOTYPE

The 24 human chromosome-specific DNA probes were used to visualize seg ments of conserved synteny on metaphase chromosomes of the American mi nk (Mustela vison). A comparison with the hitherto known gene mapping data shows a high degree of correspondence. The human chromosomes were found conserved in only 34 segments of common synteny. The mink arran gement proved to be very similar to the arrangement found in the cat, thus corroborating the well-known high karyotype conservation describe d for Feloidea.
