BREEDING SCIENCE

BREEDING THEORIES

INBREEDING

This is the mating of very close relatives.  Ex: Mother to son; father to daughter; brother to sister, etc.  Usually used by breeding experts to 'amplify' a certain characteristic of a bloodline.  This could be good, or it could be bad.

OUTCROSSING

This is the opposite of inbreeding.  It involves the mating of two dogs who have no relations in common.  The rule of thumb applies to those ancestors within four generations.  This 'fresh' blood is usually used by breeders to invigorate a bloodline.

LINEBREEDING

This method is used consistently by breeders.  It involves the mating of dogs that are related past the third generation.  Usually grandfather to granddaughter or niece to uncle.  This method is used by breeders to allow them to amplify a certain trait without the risks of inbreeding.

THE INFLUENCE OF THE DAM ON THE OFFSPRING

by Dr. Jim Gannon

Dr. Jim Gannon has penned the following to keep participants informed about important breeding issues. Let me ask the simple question -- Do the sire and dam have equal input into the inherited qualities of the litter?  Now, of course, 99% of respondents will automatically say - Yes - but is that the reality?  According to the information from Theresa Garton in Oklahoma City in USA, research has revealed irrefutable scientific evidence that challenges, and disproves, that popular traditional belief. So the real ANSWER is - that the dam actually contributes more than 50% genetically to her litter. For the scientifically minded, this is how the apparent heresy comes about: -Every structure within the body is composed of millions of tiny cells (brain cells, liver cells, kidney cells, skin cells, etc.) -Every cell has three important components - a nucleus containing the genes hidden in the coils of DNA - a membrane (like a skin) that holds the contents of the cell together-and, the cytoplasm which is a jelly-like fluid filling the cell and supporting some other structures essential to cell operation, and, to life itself. -Two of these life-support structures within the cytoplasm are the Mitochondria, and the Golgi Apparatus. Now, the egg produced in the ovary is similar to any of the other millions of cells of which the body is composed - except it has only 50% of the mother's genetic material (DNA) in its nucleus, same as the sire has in his sperm, BUT the egg also contains the mother's cytoplasmic life-support Mitochondria, Golgi Apparatus, and all of the other enzymes within the normal cytoplasm. -On the other hand, the sperm contributed by the sire contains only the usual 50% of his genetic DNA in its nucleus, plus a tail to enable directional guidance when swimming, and a short-lived energy supply for the swim-but virtually no cytoplasm. (and consequently, none of its important life-supporting Mitochondria or Golgi Apparatus structures --these come only from the brood.

Fertilization occurs when the sperm of the sire locates and enters the egg of the brood, and the newly formed cell develops into a pup over the next nine weeks. However, it becomes immediately apparent that the pup which develops from that fertilized egg will have equal DNA contributions (genes) from each parent (50% DNA from each) within its nucleus, BUT, will also have all of the essential life-support systems of the Mitochondria and Golgi Apparatus from its mother's egg within its cytoplasm -- and these are inherited ONLY from the mother. Without these life-support structures, the genes within the newly formed nucleus would never survive to reach their genetic potential --and, the efficiency of the working cell in later life will be totally dependent upon these cytoplasmic structures inherited from the brood. The RESULT is that the litter really do inherit more from the mother than the sire. The LESSON is to select the brood brood with just as much care and attention as you would for the sire. One aspect of disappointing performance from a litter sired by a top sire dog may be that many broodes are chosen for breeding on the basis of finance, family affection, emotion, and ready availability of the brood currently in the kennel. Our breeders should make note of the recommendation to the USA greyhound breeders emanating from the Oklahoma investigation - "we are faced with making sure that both parents are of the BEST QUALITY available - do not skimp when picking the brood brood in your breeding program".

-THE PEDIGREE OF HBs COMMANDER, THE AMERICAN DERBY, AND WHY RACING GREYHOUNDS RACE

by Dennis McKeon

Mostly everyone who owns a racing greyhound, either as a racing professional, or as a pet owner, has heard the story of the legendary HBs Commander. He was sired by a greyhound that few people were aware of, out of a less-than-fashionable branch of an old and classic American-based female family. While he was an extremely precocious racer, and though he eventually was stopped by injuries and surgery, he was to prove to be an absolutely revolutionary sire. He led the US sire standings from 1994-1997 inclusive, and was elected to the Greyhound Hall Of Fame in 1999, in a large measure because of his prepotency as a modern cornerstone of the breed. He passed away unexpectedly due to an annuerism, at the relatively early age of 8. His son, Molotov, who led the sire standings for 5 years, and another son, Oswald Cobblepot, a highly influential contemporary of Molotov, distinguish HBs Commander as not only a sire of fine dams-----like Oneco Malee, the dam of the mercurial Talentedmrripley----but as a sire of sires, an almost certain guarantee that HBs Commander’s influence upon the breed will be indelible.

To say that HBs Commander’s phenomenal success was unexpected at the beginning, would not be an understatement. But succeed he did, in spite of the fact that he was not exactly lionized by breeders at the outset of his career as a sire. That would come later, after it was apparent that he was throwing quite a bit of himself into many of his offspring. And despite the protestations of his detractors, there was little doubt that HBs Commander seemed prepotent toward imparting a high degree of pace and power aptitudes, as well as his own rough hewn and burly----some would say unrefined and coarse---- conformational attributes, to a great many of his progeny. Why this particular greyhound, among all his peers, and in the broader historical context of the breed, should become a sire of profound influence, is a matter for some sirey, and might never truly be ascertained, from a standpoint of hard science.

Yet, if we do a bit of research into his pedigree---- which at first glance, seems not particularly extraordinary---- we begin to understand the importance of racing, and why racing competition is so essential to the Racing Greyhound as a unique breed. Racing is what allows the breeder to place a relative value upon the quality of the stock he is producing, and the bloodlines from which he produces his stock. Racing, at it’s highest competitive levels, illuminates for the breeder, which individuals, and the families they are from, have achieved the highest levels of adaptation in response to the function of competitive racing, for the purpose of competitive racing. It allows for the most accurate and “correct” selectivity from among the racing population, as to which greyhounds, and which families of them, are best adapted and likely the most capable of carrying on with the breed, and of having input to the genepool of the Racing Greyhound.

The high degree of accuracy in selectivity of breeding specimens that competitive racing provides for the Racing Greyhound breeder, has enabled the Racing Greyhound to become perhaps the most phenomenal athlete in the history of sport. It has not been an accident, that among all large breeds of canines, only the Racing Greyhound is virtually free of the crippling defects of congenital, degenerative hip dysplasia. Nevertheless, HBs Commander imparted a certain degree of adaptational “advantage” to significant percentage of his offspring, who in turn have done the same for their offspring.

While some may see this as an accident of nature, I think that with a bit of investigation, we may begin to understand that HBs Commander was the result of generations and generations of selective breeding, cause-and-effect related to racing competition and the insight that racing at the highest levels, has provided to the breeder. He traces his direct female ancestry to the Randle Brothers’ foundation dam, Miss Judy (circa 1924, by Judas III x Irish Midget). While the female family has several distinct branches, it was another offshoot of the Miss Judy family, through Medora, the dam of Real Huntsman (by Never Roll), which was to first distinguish the line.

Real Huntsman’s legendary career, and his 2 victories in the greatest and most prestigious open stakes race in the history of the Sport Of Queens in the US----the legendary American Greyhound Derby (first run at Taunton, MA, in 1949)----remain virtually unparalleled in the history of racing. Another branch of the Miss Judy female family was to produce the foundation dam of the Beckner family breeding dynasty, Mary Moore, who is the direct female ancestor to Buzz Off, a Hall Of Fame brood matron.

The branch of the Miss Judy family from which HBs Commander descends, is divergent from both of these. It’s most profound previous expression had been the 2 time All American, Rock A Dee, by Go Rockie ( a son of 1956 American Derby winner Go Rock) x Dixie Day, a brood standings leader in her time. Interestingly enough, Hbs Commander’s sire, the unheralded and sparingly bred Akbar, traces his direct female ancestry to Je Nays Empress-----who is a direct female descendent of Medora-----the aforementioned dam of the aforementioned 1950-1951 American Derby winner, Hall of Fame inductee, Real Huntsman. Akbar’s paternal grandsire, Tara Bounder, also carries Je Nays Empress as his 2nd dam. Je Nays Empress (Ample Time x Je Nay) carries the first American Derby winner, Oklahoman, as her damsire. She is the dam of 1967 American Derby winner Xandra, by Julius Caesar.

Julius Caesar is the 2nd damsire to Kelton, who is the sire of Akbar-----and Julius Caesar is the damsire to Big Whizzer, the sire of Downing.....who is the damsire to HBs Commander . Downing is thought by many to have been the most precocious and perhaps even the fastest greyhound ever to set foot upon a racetrack in the US. In addition to his startling and legendary victories in the prestigious Hollywood World Classic, and the Biscayne Irish American-----Downing bronzed his immortality as a racer, by winning the most coveted trophy of all , with his hard fought victory in the 1977 American Derby.

So, while we may debate the state of the sport of greyhound racing today, and its place in the modern day scheme of things, there can be no debate whatsoever as to the critical importance of one single race-----The American Greyhound Derby, in the pedigree and to the immediate ancestors of HBs Commander. He is steeped in the blood of American Derby winners and their families. This single race appears to have been a highly predictable indicator of the bloodlines which were paramount in their era, and among the most worthy of perpetuation, as we can see, as an indicator of the most highly adapted and prepotent individuals who would carry them forward into this modern era. They would one day again find ample and at times, exquisite expression throughout the racing greyhound breed, through a greyhound who at first glance might seem to have been from the “wrong side” of the breeding tracks. When in actuality, he was quite adequately predisposed, by virtue of his ancestral relationships to success in the American Derby, to be both a racing and breeding “locomotive”.....HBs Commander.
