In last week’s article I discussed the inbreeding found in some real life horses, those who were stellar racehorses or sires in recent years. The majority of their pedigrees contain at least one 4×4, 4×5, or 5×5 cross. The four sires that stood out as being crossed back to most often were Bold Ruler, Nasrullah, Nearco, and Native Dancer. Since the Sim is so heavily based on real life, one would expect to find that the top runners in the sim would have similar crosses in their pedigrees. <\/FONT><\/P>

Here’s what I found when looking at the inbreeding of 40 of the top A Grade retired horses. <\/FONT>Either 4×4, 4×5, or 5×5 inbreeding to Nasrullah can be found in Enough Knock, Cecil Roo, Dusty Dance, Project Thor, Starke Storm, Horn Knee Sal, Huge Tale, Seriously Double, Western Groom, Gatling Prospector, Queen’s Cats, Green Bow, and Rakida’s Road. Similar inbreeding to Native Dancer can be seen in School Kris, Starke Storm, Seriously Double, Gatling Prospector, Storm Dog, Queen’s Cats, George’s Burglars, Duke Ali, Amanda Jane, Sal’s A Thief, Daneye, Alone That Baby, and Sunken Treasure. Those were the most commonly found crosses, but similar inbreeding can also be seen to sires like Nearctic, Hail To Reason, Northern Dancer, Bold Ruler, and Raise A Native on a regular basis. A handful of those horses even contained a 3×4 cross in their pedigree. So it appears that the same types of inbreeding that is found in the best real life runners and sires can also be found in the best retired Sim runners. And similar to real life, there were a handful of top retired Sim runners that were complete outcrosses. These included Pleasant Nijinsky, Ray Of Pye, High Devil(fr), Buda With The Slew, Blue Ant, High Cozzene, and Mississippi Gulch.<\/FONT><\/P>

Those similarities to real life did not surprise me in the least, since most of those top retired horses were bred by the computer. It seems only natural that Mike would have programmed the computer to breed horses that follow the same principals\u00a0as real life breeders. But what about horses that were bred by Sim trainers? Would the best of those show the same type of inbreeding? Would we find multiple 4×4, 4×5, and 5×5 crosses with a 3×4 cross thrown in once in awhile?<\/FONT><\/P>

So I examined 40 current runners near the top of the overall earnings list that I knew to be created by a Sim trainer. Here’s what I found. <\/FONT>The same type of 4×4, 4×5, and 5×5 crosses appeared in most of their pedigrees. Crosses to Hail To Reason can be found in the pedigree of Allied Assault, Sunnybank Memorial, Bristol Rovers, Kayla’s Missile, Krishna(ire), and Jolie’s Song. Similar crosses to Raise A Native can be seen in Tuff Enuff, I Seek U, Silver Canuck, King Of The Cats, Birchwood Medway, Danzig On Skis, Galloping Ghost, Meet The Legend, Anticosti, Horseshoe Bay, General’s Chariot, and Dubai Prospector. Northern Dancer crosses can be found in Dante(gb), Silver Canuck, Ziklag, Granhee, Kayla’s Missile, Stormy Bluff II, Birchwood Medway, Grand Caffreys, Dangerous Reward, SJ’s Silver Ghost, and Jolie’s Song. There were even a couple of examples of outcross breeding in the forms of Rain God and Squal Me Halo.<\/FONT><\/P>

But then we also find several examples of inbreeding that differ with the real life pedigrees. There are several Sim horses that have close up inbreeding in their pedigrees. Call Of The Wild II is inbred to Northern Dancer 3×3, I Seek U to Mr. Prospector 2×3, Silver Canuck to Mr. Prospector 3×3, Suzyjinsky to Northern Dancer 2x3x4, Sacrilege to Secretariat 3×3, Anticosti to Fappiano 3×3, and General’s Chariot, Dubai Prospector, and La Pata Daisy to Mr. Prospector 2×4. The worst example of this would be Squall Is A Storm, who is inbred to Storm Bird 2×2. Should this close inbreeding be held responsible for the talent shown by these runners? Probably no more responsible than the 4×4, 4×5, and 5×5 crosses that are also found in those same pedigrees. I would have thought that if close inbreeding were truly as beneficial as many Sim breeders think, it would have shown up in a much greater proportion of the Sim’s top runners. <\/FONT><\/P>

So what does all this mean? I guess we can each come to our own conclusions, but I’ll share mine with you. It’s my conclusion that it is beneficial to incorporate the real life inbreeding patterns into my own Sim breeding. Inbreeding in the fourth and fifth generations to sires like Nasrullah, Bold Ruler, Native Dancer, Raise A Native, and Northern Dancer would seem to offer the greatest chances of Sim success. <\/FONT><\/P>

But how does one construct those types of crosses? Is there more to it than just throwing three sires together and seeing what the resulting 5x pedigree would look like? Drop by next week to find out more……<\/FONT><\/P>

And that’s the story this week, from the Dog House.<\/FONT> <\/P><\/FONT><\/p>\n","protected":false},"excerpt":{"rendered":"
