Inbreeding is the result of mating between related breeding stock.
Inbreeding coefficient for the horse Geni De Lalande : 0.22 %
Coefficient based on genealogical data stored in SIRE database
Inbreeding coefficient for the breed Poney Francais De Selle : 0.46 %
This is the average inbreeding level in a reference population of thoroughbred horses PFS
(PFS nés entre 2013 et 2017 pour la consanguinité affichée en 2020)
The percentage of known ancestors per generation only takes into account ancestors for which the origin has been certified. The inbreeding coefficient has been established based on these certified origins. There can be a difference between a 3-generation pedigree and the percentage of known ancestors actually used.
|Geni De Lalande||100.00 %||100.00 %||100.00 %||100.00 %||87.50 %||79.69 %||68.75 %||42.97 %||22.66 %||10.55 %|
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%.
