Genetic diversity
Inbreeding
Sire pedigrees are analysed to determine "genetic originality". The tools proposed can help the breeder. They help avoid increasing inbreeding and maintain a sufficiently diverse pedigree.
Inbreeding is the result of mating between related breeding stock.

Inbreeding coefficient for the breed Poney Francais De Selle : 0.47 %
This is the average inbreeding level in a reference population of thoroughbred horses PFS
(PFS nés entre 2017 et 2021 pour la consanguinité affichée en 2024)
Use of the inbreeding coefficient calculation can have the following consequences:
- favourable, when it allows the expression of "interesting" genes from one or more ancestors;
- unfavourable, when it results in the accumulation of undesirable genes and their expression in the genotype.
This calculation only uses knowledge of the pedigrees recorded in the SIRE and ranges from 0 to 48.3% (average 0.8%). Half of all horses are not inbred (53% with an inbreeding coefficient = 0) 22% have an inbreeding coefficient under 1% and 23% between 1 and 5%. Only 2.5% have an inbreeding coefficient over 12.5%.
