Breed Similarity Analysis
This part of the analysis determines to which breeds a horse is genetically most similar. For this purpose, the marker values of the analysed animal are compared with the data of representatives of other breeds and a ranking list of similarity is compiled. In addition to Part I (breeds and breed groups involved), we find out here to what extent the individual genetic make-up of a horse is reflected in the recognisable horse breeds.
Horses that are listed in a breed group generally show those breeds in the list that contribute to the group in question.
There are currently 87 different horse breeds included in the analysis for similarity. A list of these breeds is available below. A breed will be included if it shows genetic characteristics and sufficient representatives have been analysed for a similarity analysis.
Please note: In horse breeding, a breed is often assigned solely on the basis of registration in a particular studbook. In such cases, the assigned breed often does not correspond to the one with the highest match in the DNA analysis and may even be missing from the list of results.
Examples:
Studbook based breed = Hanoverian, TOP 1 similarity = Oldenburger, Hanoverian is listed as TOP 4
Studbook based breed = Württemberger, TOP 1 similarity = Hanoverian, Württemberger does not appear in the TOP results
Horses that belong to one of the distinct breeds always show their breed as the TOP 1 in the similarity analysis, as well as other breed portions to a lesser extent. These ‘foreign contributions’ represent the genome components that originate from the time when the stud books were not yet closed.
By reliably determining the percentage of contributing breeds, Generatio's breed analysis is the ideal approach to accurately determine the true thoroughbred percentage of each horse. The true extent of many horse breeds is usually much higher than can be calculated from the pedigrees, as many breeds, especially all warmbloods, have a more or less pronounced basic proportion of thoroughbred genome.
