Go with… the Outbreeding
The method of outbreeding is valuable for getting away from heavy duplications in the pedigree. It acts like an outcross where one of the parents is already inbred or linebred or both. The purpose is: breed away from intense concentration. Quite effective for producing high class performance! Really, it is to maximize an overall genetic expression. That is, it is over and above reckoned pedigree duplication via linebreeding & (hopefully) plugging into recessive/latent alleles whereby best practice, targeting to newer type. The exercise can use very good but non-commercial stallions proviso the overall profile ‘gathers’ multiple, potent variable sources and or, are not just ‘fixed’ in one individual. Yet, it just ‘fits’ well & with depth it creates.

These gems can still turn up unexpectantly. The perplexing becoming more as enlightenment by the odd truth: the Bruce Lowe tables failed the best & old female lines in Northern America and actively discriminated for that astonishing theory came based in Family numbers 1 and 2 progenies allotted to England’s classic races as represented to The Figure System.
Future pedigree patterns of the racehorse depend upon the strains used by private breeders much more to than commercial breeders.

Many breeders still believe in the mathematic coefficiency table with displays a rapid decline of genetic impact from ancestors in each generation of a pedigree. The hybrid horse need not transmit anything like the tables suggest. One specific ancestor can mess up the statistics.
