Abstract

Genomic DNA was extracted from 87 dark mink from two farms in Nova Scotia. Genetic variability was assessed by DNA fingerprints generated using Hae III restriction endonuclease and Jeffreys' 33.I5 probe. The results showed a high degree of DNA polymorphism m both farms. All but one of the 22 bands scored in the range of 4 to 7.2 kb were polymorphic. The two farms were comparable for the mean number of bands per individual (6.2 and 6.8), average band frequency (0.33 in both farms), locus heterozygosity (0.51 and 0.53) and index of band sharing among individuals within each farm (0.53 and 0.54). The results suggest a higher genetic variability than expected _ based on the population number and the historic P^^val^rice of inbreeding of mink in the region. Similarity between the two farms could be due to gene flow from common sources.
