Sažetak
Mating among related animals is an inevitable consequence of a closed population structure especially when it is coincided with small census size. As a result inbreeding depression may be encountered especially for fitness traits. However, under certain circumstaces the joint effects of inbreeding and selection may at least partly purge the detrimental genes from the population. In the course of this study our objective was to determine the status of purging and to quantify the magnitude of the eliminated genetic load for the survival at birth of Pannon White rabbit kits maintained in a closed nucleus population. The evolution of the survival at birth was evaluated applying the PurgeR software based on the inbreeding-purging model. 22718 kindling records was analyzed for the period of 1992-2017. Concerning the estimated parameters purging coefficient reached the possible maximum value of 0.5 between 1992-1997. Based on the expected fitness and on the expressed opportunity of purging the beneficial effects of purging could be expected after 10 generations where the proportion of the purged genetic load could be between 20 and 70%. These results suggest that large fraction of the inbreeding load may be caused by limited number of genes that could possibly be purged.
