l l I I ' Through the on y of Dr. C. K. Gunn we are to Dr!- ,,,-ui to the many mink farmer rcauers of this column the results or his years of study on the gene- tics of mutant mink. Dr. Gunn is one of the beat. it not the best, authorities in America on the sub- ject on which hehas written, and we ltave.been endeavoring for quite a long time to obtain the scientific " 'irmation mic; :11! articles can ave. t, o - for conning: study by every mink breedt. The mink ranchers in the Unit- ed States have made great strides and the results it that they have had scientific knowledge to guide them in their operations. To the writer it has been a difficult sub- ject to obtain information on and we are grateful. and we are sure pelts our readers will be grateful, to m. Gunn for enabling us to have this sublect treated in such an intelligent and'infornsative man- ner.

Dominion Experimental Fur Ranch, Summerside. P. E. 1. PART ONE There is considerable confusion st present in the literature in respect to mutation mink because of overlapping of similar color phase of genetically different types of mink. Added to the com- plexity of the above picture is the recently adopted. new nomencla- ture given to the pelts of certain strains of mink. An attempt to clarify this con- dilloll has been made by classify- ing mink solely on color phases in some of the recent live mink shows. This is approaching the problem along lines which are ex- , plicit to the consumer puplic and ' frequently more equitable on the show table to the rancher of strains of mink with a wide range of color phasing. The question is, does this method of Judging mink give the rancher adequate ad- vertising for the sale ,of his breed- ing stock, after he has develop- ed improved strains of specific mutant types? it would seem there are two sides to this question and each has its merits. However. if a long-term view is taken it most be obvious to mink ranchers that as more mutant types of mink are discovered. new double reces- . sire blends. triple blends or quad- ruple blends developed, and still , iuriher color phases added to the .sbove types as a result of the inclusion of the Breath-of-Spring andlor Stewart factor: the color phase question (pheno-types) ver- pis that of the genetical make-up iuenotypes) will continue to be- come more and more involved in the mink ranching industry. Accordingly. it may be advisable II. this time to initiate a planned ,Dl'i)gl'flIn to meet the rapidly ap- proaching state when many strains of mink will be almost identical in color. but will represent a con- siderable number of different genctical types. The consumer public and menu- facturers are chiefly interested iii the general color and quality of a mink garment. but are not motivated by the particular geno- type producing the color of ag pelt ,nrnvided there is no apparent dif- Terence in quality of the for as a result of the different genotypes producing the same colored fur. similarly, on the show table. the ;sonfuslon will be greatly multi- gplied if each genetical strain of mink has to be allocated to a particular class based specifically on the genotype of the mink with- out due regard for the similarity (sf color in other genetical strains. Although in the present transi- tional state the allocation of dif- ferent genetical strains (geno- s) of mink to a common gnation or class based on color MW seem to impose a hardship it he breeders. it would sp- leauiiiul Tile Walls - of low Cost!

According. with this future trend in mind. it would be advis- able for mink ranchers to select strain which give pop ' color phases among those genetical strains of mink which have also. fecundity and are easiest to raise. Then a careful breeding pro- gramme should be inaugurated to improve the quality of th fur in each of -the different (color) lines of mink maintained. Careful selec- tion snd llnebreeding will give the required results in establishment of a particular strain of mink with prepoiency and uniformity in for type and quality. for the hereditary traits required to pro- duce commercialw desirable mink The following is a classification of mutant mink based on color. Thermaiu colors of which are (1) Blue. (2) Brown, (3) Beige and (4) White types. 1. Blue Types Mutations - Imperial Platinum; Steelblu; Platinum; Aleutian: Blue Iris factor (Recessive types).

Triple Blends - Kohinur - Sap- Kohinur (Black Cross) White mink (Note: Palo-Pastel is a dark (standard) mink dlhybrid for the Palomino and Pastel factors). NAMES AND Name Ungava Pastel Ungava Ruby-eyed Pastel Stewart Factor is a dominant modifying factor which not only lightens the existing color of a mink strain. but imparts a clear- er bluish tlnge to the existing fur color. This factor can be pres- ent in the hybrid state. giving rise to pale pelts or in the hom- ozygous state (called "Homo"). in which the pelts then are extra pale. Pole and extra pale shades are in vogue at the writing of this material and demand the highest market values among mutation mink pelts. However. when the dominant Stewart factor is present in the homozygous state, it usually causes such mink to become ster- ile. especially in the male sex. This defect of the Stewart types should be taken into considera- tion before mink ranchers intro- duce this factor into a prolific strain of mutant mink if the de- sired lighter coloration can be obtained in another natural mut- ant strain of mink. Occasionally, a Stewart type mated ,to Stewart type produces an all white mink. This white type. however, is sterile, With the ad- dition of the Stewart factor and) or Breath-of-Spring in conjunction with the natural or inherent varia- tion of mink pelts. they can be subdivided into the following five colors phases: Dark ) Medium ) Inherent Natu ral ) Variation. Light ) Pale - (Heierzygous) Ste- P wart Factor andlor Breath-of-Spring. lxtra Pale - (Homozygous) - Stewart Factor. in view of the five possible variations in color phasing which can be produced with each mut- ant and each blend of mutant plete to date). phires; (Kohinur x Platinum x Triple Blends - Winterblu (Roy- Aleutian). .

To obtain such blends. two different recessive mutant types are mated together in the first cross. the progeny from which are all dark mink but carriers of both recessive mu- tant factors or dihybrids. In the second cross. these dihy- brids are mated together and. in one chance out of sixteen. both pairs of the recessive genes of the two parents will allocate in the same kit. giving in the new characteristics of a result- ant blending effect of both reces- sive mutations in the same ani- mal. Examples (1) and (2). as follow, show the tw steps in cross- ing two recessive types together in order to derive the genotype with the double recessive blend of fur colour. (1) Platinum (Silverblu) x Aleutian (10096 dark dihybrid) (2) If the above dihybrid ani- mals are mated together there is a probability of obtaining one double recessive blend in 16 pro- geny and the following colored (phenotyplc) :- No. Kind 1 Sapphire mink (Double recessive) 9 Standard mink 3 Aleutian mink 3 Silverblu mink. A similar ratio will result when other recessives are crossed as above. That is. there will be 9 standard. 3 of each of the two ori- ginal parental types and one double recessive blend.

If the dihybrids used in the second cross are each carrying a single Stewart factor. then 7596 of the 16 genotypes will be of Stewart marked and 2596 of these Stewarts will be homozy- gous (homo) for this factor. The Stewart marked types can readily be detected'by their light and ex- tra light color phases. , An example of the genetical types (genotypes) which result from a triple recessive blend, such as that of Sapphire crossed with Royal Pastel, to give the new triple recessive, called "Winter- blu" is shown on page 45 in the publication il27.s"Mink Reaching" and this Sapphire mink crossed with Royal Pastel gives the fol- lowing numbe r and types;- No, Types of Mink Dark (Standard) Mink Royal Pastels Silverblu Aleutians Sapphire: (Silver- blu-Aleutian blends) Erics (Royal Pastel- Aleutian blends) Platinum Blond (Royal Pastel-Silverblu blends) Winterblu (triple reces- sive type) An easier method to insure the production of "Pearl" mink is to start with an initial cross of a Palomino male with a number of Sapp” e female This first cross producers rk trihybrids, carrying factors for the three re- t-I 5-!

Cross the trihybrids back to sapphires gives 2596 dark, 2596 Aleutian. 2596 Silverblu and 2596 sapphires. (Note:- 5096 of these Sapphire mink are carriers of the Palomino factor. accordingly, cross all Sap- phires among themselves . (half brother x half sister matings). From such crosses, the probab- ility of producing a Pearl is one in four. However, the crosses of sapphires would include those of Sapphire 3: Sapphire. Sapphire (carrier of Palomino) x Sapp” :. and Sapphire (carrier of Palo- mino) x Sapphire (carrier of Palo- mino). Only the last cross (l.e. the car- riers of Palomino) preduce the "Pearls" and accordingly. from the above three types of crosses "Pearls" would occur on the aver- age in one out of twelve kits. This methd increases the prob- ability for obtaining Pearls more than five times over the trihybrid x trihybrid method, which is one in sixty-four. (Note:- This shorter method to obtain a triple recessive blend can be used with any of the other combinations of double recessive blends and a recessive mute type as listed above). .

We next saw them rolled flat. then tossed against an angle board, that started rolling them into rolls about two and one half inches in diameter. which when dropped into the baking pan left about one inch space at each end of the roll of dough. Each process was automatic throughout except that as the roll of dough dropped into the bake pan. occasionally, the attendant who was always present. would pick out a lump of dough double size or two stuck together. or two rolls would drop in the one pan. He would then pick one out and place it in an empty pan which moved on with the others in a con- tinuous stream on the metal con- veyors that carried and placed them in the wheeled stacks where they were first placed at the cor- rect temperature so the dough would rise and fill the pan in sixty-five minutes. .
