Abstract: Brazilian hair sheep constitute a genetic diversity hotspot. These animals are found in theharsh environments of the Brazilian Northwest (semi-arid) region. Genotypes (50K SNPchip) from seven Brazilian sheep breeds (five hair and two coarse wool types) and 87worldwide breeds were used to test for population structure, admixture and geneticdiversity. Moreover, phylogenetic trees evaluating migration events between genetic groupswere built. Brazilian Somali, a fat-tailed breed, had a close relationship with East Africanbreeds and clustered distinctly from other Brazilian breeds. Brazilian Blackbelly andBarbados Blackbelly had a close relationship. The Morada Nova breed did not show closerelationships with European or African breeds, revealing a single migration event from anAlgerian hair breed. Brazilian Fat-tail and Morada Nova share a common ancestor, but theformer showed introgressions from Brazilian Somali and Afrikaner breeds, explaining thefat-tail phenotype. The Santa In^es breed received a substantial contribution from BrazilianBergamasca and showed an admixed origin with recent introgressions from other breeds,mainly from Suffolk. Furthermore, Brazilian Somali and Brazilian Fat-tail are the mostendangered sheep genetic resources in Brazil and should be the focus forex situconservation programs. In conclusion, Brazilian hair sheep show an African origin and arecharacterized by diverse genetic composition, reinforcing the need for conservation of thesegenetic resources, and at the same time, this highly diverse group has variability that can beused in breeding programs.
