For a theory - First the expedient variant of selection of paternal pairs and effective methods of estimation at creation of minks of the coloured type is experimentally set pastel with the desired middle tint of colouring of fur and the prospects of the rational use of gene pool of these animals in subsequent work for the receipt of highly productive herd of beasts are grounded. 2.
