A year or so ago another company that I am associated with, Performance Genetics, did a private study on mitochondrial DNA, the strand of DNA that is maternally inherited in all species and can be used to classify female lineages. We were specifically looking into the #1 family of Tregonwell's Natural Barb which is now that of the likes of Black Caviar, Super...

We've reached back into the time vault and unearthed a TrueNicks webinar that we filmed back in 2009. While it is over three years old, much of what we talked about back then is still relevant today. Enjoy! Click here to download the "Top 10 Myths About Nicks in Thoroughbred Breeding" whitepaper .

The interpretation of Thoroughbred pedigrees is no simple matter. The multi-factorial elements that might be considered include nicks, inbreeding, linebreeding, the positions of ancestors relative to one another, the relationship of the pedigree to the female line, and the class of the individuals involved. Given the volume of the data, and the difficulty of...

The wins of Orb in the Kentucky Derby (gr. I) and Princess of Sylmar in the Kentucky Oaks (gr. I) further solidified the pensioned Lane's End stallion A.P. Indy as the premier sire line source of classic speed in the North American Thoroughbred. Indeed, with Normandy Invasion (by Tapit ( TrueNicks , SRO )), Dreaming of Julia, and Revolutionary (out of an A.P...

15.33%. That's the coefficient of relatedness between Frankel and Chrysanthemum, the first mare scanned in foal to the champion racehorse during his first season at stud. As a point of comparison, first cousins are 12.5% related and half siblings are 25% related. Chrysanthemum, owned by the Coolmore team of Tabor, Magnier, and Smith, won a pair of group III races...

It would be reasonable to suggest that while time may prove Coolmore stallion Galileo superior to his breed-shaping sire Sadler's Wells, with the exception of siring a group I winner over 4000m (which Sadler's Wells did in the form of the brilliant Yeats), right now Galileo is every bit as good a classic sire as his father. Like many elite stallions, Galileo...

There are few topics in the world of pedigree theory—and for that matter in the Thoroughbred community as a whole—that are more emotive than the subject of inbreeding. On one hand, inbreeding, and what is perceived as a consequential decline in genetic variety, is blamed for all manner of ills including a supposed decline in soundness. On the other, it has been...

Jim Squires wrote an interesting article that appeared in The New York Times over the weekend. Commenting on the newly-in-foal Rachel Alexandra and Zenyatta, " Breeders Chasing the Superhorse " references nicking theory several times in the piece. While the simplicity of Squires's nicking explanation is a bit misleading as he doesn't touch on the statistical...

I have just finished reading Thoroughbred Breeding: Pedigree Theories and the Science of Genetics by Dr. Matthew Binns and Mr. Tony Morris, and it is a thoroughly interesting and worthwhile read. I can recommend it for anyone involved in breeding racehorses (see it at Amazon.com ). The book covers a large range of topics within Thoroughbred breeding as it relates...

Readers: I'm curious to get your analysis of the Sadler's Wells/Mill Reef nick. Why do you think this nick works? Avalyn Hunter ends her Mahubah's Corner column this week with a look at the combination of Sadler's Wells/Mill Reef: "…Irish Derby runner-up Midas Touch stayed on very well through the stretch and according to jockey Colm O’Donoghue may be a live...

Before being made available to the public, TrueNicks was tested on a group of more than 100,000 horses. That study firmly established a correlation between a high nick rating and success at stakes level: in fact, while only 13% of the population earned a variant rating high enough to qualify for a rating of A or better, 37% of stakes winners achieved that rating...

Reader's question: My mare Pebbles Delight has an A++ wih Corinthian. She has been accepted to his book for 2009. However, since she doesn't have a lot of black type up front, I probably won't make any profit on the resulting foal. What are your thoughts on this mating? I love the mating, but my pocketbook needs to rule rather than my heart. Sally. Byron's reply...

Jeri from New York asked: I'm pleased to see Empire Stud signed up! Could you ask Alan Porter if there is any value to tying to inbreed to Alydar. I do not see his name come up in pedigrees anymore and I have mare by Western Expression whose bottom has Alydar mate of third dam. I may be going back to far, but I could not help but think of the great horse himself...
