[Mono- and polymorphic blood protein loci in mink (Mustela vison Schr.)]

Heterogeneity of haemoglobin, albumin, transferrin, esterase, alkaline and acidic phosphatases, haptoglobin, post-albumin, ceruloplasmin, carboanhydrase was studied in 1501 standard and colour minks by means of starch gel electrophoresis. Only the last three proteins of the enumerated ones have hereditary variations. Frequencies of the "main" allels of these systems are not lower than 0.9 and the average heterozygosis is 0.023.
