Inbreeding and Relatedness Coefficients extended to 10 generations

Monday, February 04, 2019 11:29 AM

This morning you may see that we have extended the computations of the Coefficient of Inbreeding and Coefficient of Relatedness to 10 generations. These coefficients were previously calculated over 8 and 6 generations respectively and were done to that generation previously due to computational restrictions, i.e, the speed of the computers and the frequency of...

The Disappearance of Dosage

Monday, December 10, 2018 9:14 AM

A couple of weeks ago the manager of a TrueNicks enrolled stallion called to tell us that a hypothetical mating had generated Dosage Figures that were all zeroes – zeroes for each category in the Dosage Profile; a Dosage Index of zero; and a Center of Distribution of zero. A check confirmed that this was not an error, and nor was it the result of an obscure pedigree... Read More...

mtDNA and Tregonwell's Natural Barb

Monday, October 20, 2014 1:48 PM

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... Read More...

Kissing Cousins: Australia and Taghrooda

Sunday, June 08, 2014 10:20 AM

Last week saw the running of the Epsom Oaks (Eng-I) and Derby (Eng-I), two of the longest existing classic races in the world and for many the barometer of the Thoroughbred breed. The Derby was won in devastating fashion by the royally bred Australia. A son of the good racehorse and now leading sire Galileo ( TrueNicks ), Australia is out of Ouija Board, one... Read More...

Return to the Sire the Best Blood of His Dam

Tuesday, October 15, 2013 5:00 PM

The breeding maxim " Return to the sire the best blood of his dam " has been attributed to longtime Darby Dan Farm manager Olin Gentry. Gentry wasn't the first to suggest this breeding theory, indeed there is evidence to suggest that it first came into livestock management via the Bedouins in upgrading Arabian stock centuries ago. The theory is that when mating... Read More...

Will Take Charge's Resilience Pays Off in Travers

Friday, August 30, 2013 7:00 AM

Classic trials apart, in the U.S. the championship-defining contests for straight 3-year-olds are usually the three Triple Crown events plus the Haskell Invitational (gr. I) and the Travers Stakes (gr. I). Prior to the weekend, the first four events had taken place and had been won by four different horses: Orb (Kentucky Derby, gr. I), Oxbow (Preakness Stakes...

Departing Adds to Confidence on War Front/Pulpit Cross

Friday, August 16, 2013 11:20 AM

While there is no doubt that nicks tend to run in sire lines, we've also often found it profitable to consider the dam of a stallion when attempting to predict potential crosses. For example, when Smart Strike ( TrueNicks ) retired to stud, we noted that he was a half brother to champion Dance Smartly, a daughter of Danzig. Since Smart Strike was a Mr. Prospector...

Galileo/Danehill Revisited

Thursday, July 18, 2013 12:45 AM

A little over two years ago, we looked at the cross of Galileo with mares by Danehill . This was fast becoming a European mega nick, having—in the space of three weeks—been represented by Frankel, who had just taken the Two Thousand Guineas (Eng-I) in breathtaking style; Golden Lilac, successful in the French One Thousand Guineas (Fr-I); and Roderic O'Connor...

A Classic Case of Coincidence?

Wednesday, May 29, 2013 10:40 AM

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... Read More...

Frankel's First Mating: Lots of Inbreeding

Monday, March 04, 2013 7:00 PM

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...

Frankel Highlights Success of Danehill Mares

Monday, October 22, 2012 11:00 AM

On a week when much will be written about the great Frankel (Galileo– Kind , by Danehill) as he retires to Juddmonte Farms to serve his first season at stud in 2013, this writer had pause to reflect on the outstanding performance of his broodmare sire, Danehill, who has thus far proved himself a phenomenon as a sire and broodmare sire in two hemispheres—a true...

With Danedream flashing her credentials for a shot at back-to-back victories in the Prix de l'Arc de Triomphe (Fr-I) with a score in the Grosser Preis von Baden (Ger-I) at the weekend, we thought it was worth a look back at her pedigree from this article we wrote for the International Thoroughbred after her win in the King George VI & Queen Elizabeth Stakes in...

Gary Hadden Discusses Mating of Reckless Abandon

Thursday, August 23, 2012 5:00 PM

Last weekend was an exciting one for bloodstock consultant Gary Hadden ( haddenbloodstock.com ). Gary recommended the mating that produced Reckless Abandon, a son of Exchange Rate ( TrueNicks , SRO ) who won Sunday's Darley Prix Morny (Fr-I) and solidified himself as the top European 2-year-old. The colt previously took the Norfolk Stakes (Eng-II) at Royal Ascot... Read More...

Kauai Katie: Repeating the Pattern

Thursday, August 16, 2012 11:30 AM

It's still very early in the season for serious juvenile competition, but there is no doubt that one of the most impressive 2-year-old fillies seen to date is Kauai Katie. Successful by 12 lengths on her debut ( video ), the Stonestreet Stable color-bearer returned to action at Saratoga in the Adirondack Stakes (gr. II), and captured the 6 1/2-furlong event by...

Chichicastenango's Never Bend Affinity

Wednesday, June 13, 2012 4:45 PM

A few weeks ago, when looking at the emerging French second year sire Turtle Bowl , we noted that he conformed to something of a recent trend in France, the appearance of a number of good sires with relatively unfashionable pedigrees, other examples that come to mind including Linamix (by Mendez), Muhtathir (by Elmaamul), and Chichicastenango (by Smadoun).

Taking Charge of the Pedigree

Thursday, April 05, 2012 4:45 PM

The most recent weekend saw two Kentucky Derby (gr. I) preps with $1 million purses, and both resulted in upsets. The Florida Derby (gr. I, video ) seeing longtime Derby favorite Union Rags and the well-regarded El Padrino finish third and fourth, respectively, behind gate-to-wire scorer Take Charge Indy. The Louisiana Derby (gr. II, video ) fell to another pacesetter... Read More...

Deconstructing Black Caviar

The brilliant victory of Black Caviar in the MRC C.F. Orr Stakes (gr. I, video below) - which took her record to 18 wins in 18 starts - gives us an excuse to post an article of her pedigree that ran in the Australian publication Inside Breeding last year, which explored the potential reasoning behind the mating that led to her. Why is Black Caviar brilliant?... Read More...

It's All Relative

Friday, February 05, 2010 11:22 AM

Last weekend was relatively light on graded stakes action in the U.S., with just three races at that level. Two of the three, however, went to horses with interesting genetic relative inbreeding. Medaglia d'Oro ( TrueNicks , SRO )’s “other” grade I winning filly, Gabby’s Golden Gal, took her second race at that level, the Santa Monica Handicap (gr. I). She is... Read More...

A Crowded Family Portrait

Tuesday, January 26, 2010 2:46 PM

We have to wonder if there has been a more prolific family in the last couple of years than that of the Verbatim mare, Right Word, the dam of three stakes winners: the graded scorer Ascutney and Words of War (both by Lord At War) and Word o’ Ransom (by Red Ransom). Ascutney is dam of two graded winners, headed by Raven’s Pass, winner of the 2008 Breeders’ Cup... Read More...

It’s only the third week in January, but the classic generation are already beginning to crank up. As far as the Derby is concerned the most significant race was the San Rafael Stakes (gr. III).

What's the Difference?

Sunday, January 10, 2010 12:30 PM

Russell asks : Why are the ratings found in the Stallion Affinity Report not the same as the ratings obtained by running an individual mating? As an example, Storm Cat over Yonaguska gets a TrueNicks rating of A+ according to the sample affinity report shown for Storm Cat. I ran my Yonaguska mare, Bella Cherokee, with Frost Giant using the TrueNicks link on the... Read More...
