Webbture and a run of homozygosity analysis disclosed low in-breeding compared to normally feathered chickens (Elbeltagy et al. 2024). This genetic structure is likely associ-ated with breeding history notwithstanding carrying Na. For example, the normally feathered Fayoumi and Dandarawi have been intentionally selected to develop native breeds; WebbHowever, inbreeding in the moose population manifests in the form of intermediate-length runs of homozygosity suggestive of historical inbreeding and purging, contrasting with the long runs of homozygosity observed in the smaller wolf population. Using simulations, we confirm that substantial purging has likely occurred in the moose population.
