    Constructive Breeding II – The Color-Type Method

    [FONT=Arial,Helvetica,adobe-helvetica,Arial Narrow]http://hometown.aol.com/sportingdog100/page5.htmlConstructive Breeding II – The Color-Type Method [/FONT]
    [FONT=Arial,Helvetica,adobe-helvetica,Arial Narrow]by Lawrance D. Mahomes[/FONT]​

    [FONT=Arial,Helvetica,adobe-helvetica,Arial Narrow]For thousands of years, breeders of plants and animals have used breeding methods to [/FONT][FONT=Arial,Helvetica,adobe-helvetica,Arial Narrow]produce favorable combinations of genes. These “genetic engineers†have produced most[/FONT][FONT=Arial,Helvetica,adobe-helvetica,Arial Narrow] of the economically important varieties of flowers, vegetables, grains, cows, horses, cats[/FONT][FONT=Arial,Helvetica,adobe-helvetica,Arial Narrow] and dogs.[/FONT]

    [FONT=Arial,Helvetica,adobe-helvetica,Arial Narrow]Breeding with the Color-Type Method – one must start with or acquire foundation stock or [/FONT][FONT=Arial,Helvetica,adobe-helvetica,Arial Narrow]breed (create your own) foundation stock from the absolute best Genetic Gene Pool [/FONT][FONT=Arial,Helvetica,adobe-helvetica,Arial Narrow]available. Then implement the Color-Type Method of breeding for the expeditious [/FONT][FONT=Arial,Helvetica,adobe-helvetica,Arial Narrow]development of a line/strain/family for this is one method by which one who is not well [/FONT][FONT=Arial,Helvetica,adobe-helvetica,Arial Narrow]versed in genetics can create a line/strain/family. Breeding with this method one can [/FONT][FONT=Arial,Helvetica,adobe-helvetica,Arial Narrow]segregate desired traits and fix those traits quickly. [/FONT][FONT=Arial,Helvetica,adobe-helvetica,Arial Narrow]This is achieved by breeding the [/FONT][FONT=Arial,Helvetica,adobe-helvetica,Arial Narrow]same colored and type (genotype) specimens within a line/strain/family (close bred from [/FONT][FONT=Arial,Helvetica,adobe-helvetica,Arial Narrow]the same stock), black to black, brindle to brindle, red to red, white to white, etc.., [/FONT][FONT=Arial,Helvetica,adobe-helvetica,Arial Narrow]remember starting with a good foundation stock is essential. Once the desired [/FONT][FONT=Arial,Helvetica,adobe-helvetica,Arial Narrow]characteristics and conformity are attained, one should line-breed, producing exceptional [/FONT][FONT=Arial,Helvetica,adobe-helvetica,Arial Narrow]progeny (off-springs) with consistency.[/FONT]

    [FONT=Arial,Helvetica,adobe-helvetica,Arial Narrow]The Color-Type Method in detail – the breeding of like characteristics, most off-springs [/FONT][FONT=Arial,Helvetica,adobe-helvetica,Arial Narrow](siblings) of the same color and type, carry close genetic make-up (genotype), hence the [/FONT][FONT=Arial,Helvetica,adobe-helvetica,Arial Narrow]Color-Type Method of breeding. By segregating like characteristics and breeding the like [/FONT][FONT=Arial,Helvetica,adobe-helvetica,Arial Narrow]characters together, the traits are fixed with rapidity (genetically fixed). This is how [/FONT][FONT=Arial,Helvetica,adobe-helvetica,Arial Narrow]distinct lines/strains/families are created from common foundation/stock. The practical [/FONT][FONT=Arial,Helvetica,adobe-helvetica,Arial Narrow]universality of the Color-Type Method was proved by the cattle industry many years ago [/FONT][FONT=Arial,Helvetica,adobe-helvetica,Arial Narrow](used to create new strains of cattle). Also used to create pure strains of lab animals [/FONT][FONT=Arial,Helvetica,adobe-helvetica,Arial Narrow]such as mice, rabbits, rats etc... This method has been used to produce pure lines, [/FONT][FONT=Arial,Helvetica,adobe-helvetica,Arial Narrow]consistent from generation to generation with a quantitative measurement of the [/FONT][FONT=Arial,Helvetica,adobe-helvetica,Arial Narrow]inheritance of ability. [/FONT]

    [FONT=Arial,Helvetica,adobe-helvetica,Arial Narrow]• Example:[/FONT][FONT=Arial,Helvetica,adobe-helvetica,Arial Narrow] Rod Kershner began his strain of Bulldogs in 1989, from the best of Don [/FONT][FONT=Arial,Helvetica,adobe-helvetica,Arial Narrow]Mayfield/Tudor's dogs. Today 14 years later the strain that they started over 100 year ago [/FONT][FONT=Arial,Helvetica,adobe-helvetica,Arial Narrow]is still continuing at Rod Kershner's yard.[/FONT]
    [FONT=Arial,Helvetica,adobe-helvetica,Arial Narrow]Kershner's Dogtown now just produced the fourth generation of some of the purest dogs [/FONT][FONT=Arial,Helvetica,adobe-helvetica,Arial Narrow]alive. [/FONT]
    [FONT=Arial,Helvetica,adobe-helvetica,Arial Narrow]The knowledge that Don Mayfield got from Earl Tudor, he passed on to Rod, and he [/FONT]
    [FONT=Arial,Helvetica,adobe-helvetica,Arial Narrow]has been doing that for over fourteen years now. This blood has been highly respected [/FONT]
    [FONT=Arial,Helvetica,adobe-helvetica,Arial Narrow]by most breeders around the world and you can find it in every Bulldog today, but not [/FONT]
    [FONT=Arial,Helvetica,adobe-helvetica,Arial Narrow]many keep up the same high quality breeding.[/FONT]
    [FONT=Arial,Helvetica,adobe-helvetica,Arial Narrow]His family of dogs is guaranteed quality, coming from some of the purest dogs of today.[/FONT]​

    [FONT=Arial,Helvetica,adobe-helvetica,Arial Narrow]His base is Kershner's [/FONT][FONT=Arial,Helvetica,adobe-helvetica,Arial Narrow]OR-NOT[/FONT][FONT=Arial,Helvetica,adobe-helvetica,Arial Narrow] , who is not one, but the only Pure Blooded Mayfield dog[/FONT][FONT=Arial,Helvetica,adobe-helvetica,Arial Narrow] alive. Owning a dog from Kershner's Dogtown it is like owning a part of history. (take a [/FONT][FONT=Arial,Helvetica,adobe-helvetica,Arial Narrow]look at Kershner's dogs to see the Color-Type Method in action)[/FONT]
    [FONT=Arial,Helvetica,adobe-helvetica,Arial Narrow]http://tecnored.net/dogtown/history.htm[/FONT]


    [FONT=Arial,Helvetica,adobe-helvetica,Arial Narrow]Genealogy rather than genetics – one should never use the Color-Type Method of [/FONT][FONT=Arial,Helvetica,adobe-helvetica,Arial Narrow]breeding on the basis of genealogy alone. Many so-called breeders are caught-up in the [/FONT][FONT=Arial,Helvetica,adobe-helvetica,Arial Narrow]breeding of pedigrees and not on the merit of the individual animals being bred together. [/FONT][FONT=Arial,Helvetica,adobe-helvetica,Arial Narrow]Because certain lines/strains/families are more numerous and hence tend to produce [/FONT][FONT=Arial,Helvetica,adobe-helvetica,Arial Narrow]more of exceptional class and various qualities ascribed to the different [/FONT][FONT=Arial,Helvetica,adobe-helvetica,Arial Narrow]lines/strains/families responsible for successful dogs (and breeding programs) is precisely[/FONT][FONT=Arial,Helvetica,adobe-helvetica,Arial Narrow] why the frequent recurrence of some individuals are in the pedigree of noted dogs. The [/FONT][FONT=Arial,Helvetica,adobe-helvetica,Arial Narrow]pedigree breeder may sometime yield satisfactory results – but selection based on [/FONT][FONT=Arial,Helvetica,adobe-helvetica,Arial Narrow]ancestry compares unfavorably with selection based on individual merits. While it is true, [/FONT][FONT=Arial,Helvetica,adobe-helvetica,Arial Narrow]the pedigree is a blueprint of ancestry, one must place great reference on the individual [/FONT][FONT=Arial,Helvetica,adobe-helvetica,Arial Narrow]merits and their capacity as athletes as well as producers before mating individuals [/FONT][FONT=Arial,Helvetica,adobe-helvetica,Arial Narrow]regardless of their pedigrees, Many breeders today select prospective mates largely, if [/FONT][FONT=Arial,Helvetica,adobe-helvetica,Arial Narrow]not primarily, on the basis of pedigrees only. Breeders should always start with the best [/FONT][FONT=Arial,Helvetica,adobe-helvetica,Arial Narrow]possible gene pool; one must take care to choose the very best from that gene pool.[/FONT]

    [FONT=Arial,Helvetica,adobe-helvetica,Arial Narrow]Breeding the foundation/stock – based upon a supposed optimum in the proportions in [/FONT][FONT=Arial,Helvetica,adobe-helvetica,Arial Narrow]which lines/strains/families should be combined- a system “nick†or combination of [/FONT][FONT=Arial,Helvetica,adobe-helvetica,Arial Narrow]bloodlines which already has produced exceptional dogs i.e.…Alligator/Jeep cross, [/FONT][FONT=Arial,Helvetica,adobe-helvetica,Arial Narrow]Alligator/Eli cross, Jeep/Red Boy cross, Patricks/Jeep cross, etc…. One can use [/FONT][FONT=Arial,Helvetica,adobe-helvetica,Arial Narrow]elementary principles of genetics to examine the ancestry of the dogs that made these [/FONT][FONT=Arial,Helvetica,adobe-helvetica,Arial Narrow]combinations successful. This is where the pedigree becomes an important tool in ones [/FONT][FONT=Arial,Helvetica,adobe-helvetica,Arial Narrow]breeding program-the biological handicap or genetic predication index. Examination of the[/FONT][FONT=Arial,Helvetica,adobe-helvetica,Arial Narrow] ancestry, the individual, his parents, his sibs and half sibs, a pedigree at this point [/FONT][FONT=Arial,Helvetica,adobe-helvetica,Arial Narrow]makes it more effective in predicting genetic probability and quantitative measurement of [/FONT][FONT=Arial,Helvetica,adobe-helvetica,Arial Narrow]the inheritance of ability, especially when using the Color/Type Method.[/FONT]

    [FONT=Arial,Helvetica,adobe-helvetica,Arial Narrow]Environmental Factors – after one is satisfied with the line/strain/family, one must keep in[/FONT][FONT=Arial,Helvetica,adobe-helvetica,Arial Narrow] mind the environmental factor. The array of genes (genotype) may produce different [/FONT][FONT=Arial,Helvetica,adobe-helvetica,Arial Narrow]characters if the individuals carrying them develop in different environments, “phenotypeâ€- [/FONT][FONT=Arial,Helvetica,adobe-helvetica,Arial Narrow](the visible properties of an organism that are produced by interaction of the genotype and[/FONT][FONT=Arial,Helvetica,adobe-helvetica,Arial Narrow] environment) the genes act as the regulator or modulators of this interplay. The range [/FONT][FONT=Arial,Helvetica,adobe-helvetica,Arial Narrow]varies with the character under consideration and may in some cases be very wide, as in [/FONT][FONT=Arial,Helvetica,adobe-helvetica,Arial Narrow]the case of size in which the same genotype may result in small size if some essential for[/FONT][FONT=Arial,Helvetica,adobe-helvetica,Arial Narrow] requirements is withheld, or much greater size if all essential requirement for maximum [/FONT][FONT=Arial,Helvetica,adobe-helvetica,Arial Narrow]growth are freely available. It is from such consideration that the general principles is [/FONT][FONT=Arial,Helvetica,adobe-helvetica,Arial Narrow]derived which states that what is inherited is the potentiality of response during [/FONT][FONT=Arial,Helvetica,adobe-helvetica,Arial Narrow]development to a range of environmental conditions (reasons some lines/strains/families [/FONT][FONT=Arial,Helvetica,adobe-helvetica,Arial Narrow]change over a period of time/distance/location). Note: Sporting Dog Kennels, Inc. [/FONT][FONT=Arial,Helvetica,adobe-helvetica,Arial Narrow]comparative data (data complied since 1975) from random bred and inbred lines, and from[/FONT][FONT=Arial,Helvetica,adobe-helvetica,Arial Narrow] crosses between inbred lines, indicates the practical universality of heredity using the [/FONT][FONT=Arial,Helvetica,adobe-helvetica,Arial Narrow]Color-Type Method of breeding.[/FONT]

    [FONT=Arial,Helvetica,adobe-helvetica,Arial Narrow]One must reiterate, at this point, starting with the absolute best genetic gene pool is [/FONT][FONT=Arial,Helvetica,adobe-helvetica,Arial Narrow]essential, for there are many individuals that have purchased dog (for the expressed [/FONT][FONT=Arial,Helvetica,adobe-helvetica,Arial Narrow]purpose of breeding their own line/strain/family) that have magnificent pedigrees but are [/FONT][FONT=Arial,Helvetica,adobe-helvetica,Arial Narrow]dumbfounded when they fail to produce any exceptional off-springs. One must keep in [/FONT][FONT=Arial,Helvetica,adobe-helvetica,Arial Narrow]mind the hallmark of the American Pit Bull Terrier, his gameness, soundness and [/FONT][FONT=Arial,Helvetica,adobe-helvetica,Arial Narrow]campaigning ability are the attributes most highly valued. It is these attributes that have [/FONT][FONT=Arial,Helvetica,adobe-helvetica,Arial Narrow]kept this great breed pure and free from the importation of foreign blood (blood from other [/FONT][FONT=Arial,Helvetica,adobe-helvetica,Arial Narrow]species of dog), genetic defects and precisely why using the Color-Type Method, one is [/FONT][FONT=Arial,Helvetica,adobe-helvetica,Arial Narrow]still able to create new lines/strains/families, crosses and combinations that breed true.
