Aligning the well-bred phenotype and identifying super star potential is much about what are the desirable bloodline strains. The thoroughbred creation is hybrid-complex for the overtures ranges upon genuine influences.

TBL post Seattle Slew goes to explore where Slew’s genetic influence (dominant) throws. The Bernardini daughter features: Nysos – Nyquist – Zetta Z (4×5 Fappiano)by broodmare sire Bernardini (pedigree)

Nyquis’s sire Uncle Mo the descendant tail-male Grey Sovereign distinguishes some unknown eternal quality factor of Caro – the Precipitation influence + Fortino’s Relic influence where a defining Overview @ #Godolphin Arabian hence gathers bloodline Type structure. Further (@ Seattle Slew went to War Admiral daughters affixing #Godolphin Arabian pheno)

Caro to Unbridled Song > Nysos Caro 6sx6d.

Caro was something of an odd man (or horse) out in the breeding world of the late 1970s. (Link article)

Seemingly, its often-remarked Unbridled Song got ‘faults’: these Caro tail-male descendant sires numerously claimed as unremarkable (?)

Nutting it down it shall seem the basic problems overtures to a Type attribute: causes gets 2yo ‘big’ horse bred type as raced on demand. Rather than calling caution its about Discernment.

@ line-bred, the 19xNasrullah – 14x Princequillo cross goes basis to Speed and stamina. The Princequillo sons and daughters prime the Nysos profile and not forgetting Princequillo daughter Cequillo is dam of bold influence Fappiano (Nysos 5×6) and 3rd dam of Quiet American (4×3 Cequillo).

Cequillo b/m sire Mahmoud (f.f.9-c) assigns #L1aHaplotype with that of Nasrullah where Mahmoud’s phenomenal influence impacts so heavily many more than just amongst from Northern Dancer & pointedly to Nysos pedigree Glorious Song (CAN) (you can compare types, Caro & Mahmoud). Nysos 8x Mahmoud.

Haplotype L3a1b strikes through families 8c – Uncle Mo, Storm Cat, Red God, Bold Commander.

Haplotype I2a1 belonging to – Siberian Express, Forestry, Mr Prospector,

Count Fleet (Nysos 5x). Aside from his influence to Mr Prospector it would seem these days overlooked from other available lines from his daughters. The Triple Crown winner was a fine racing specimen & in his own right he reminds one of the Sundridge pheno. Pay homage to his pedigree specimens of gold: Sundridge (2x Sanda) – The Tetrarch, the 7x Lexington daughters with 7x Harkaway influence

And so delivers the super elite…
