Selection Signatures in Italian Goat Populations Sharing the "<i>facciuto</i>" Phenotype.

ABSTRACT: Background: The presence of light-pigmented facial stripes, parallel on both sides of the cranial region, is a widespread characteristic in various goat breeds of European origin and beyond. In Italy, this phenotype is relatively common from the north to the south of the peninsula. The availability of genotypic data at single-nucleotide polymorphism (SNP) loci for breeds and populations characterized by such a pigmentation pattern enabled us to study the genomic regions potentially correlated with this phenotype, for simplicity referred to as "facciuto". Methods: We adopted an F_ST-outlier approach to detect signals of differential selection in 18 pairwise comparisons, each involving 6 genetic goat types with the "facciuto" phenotype (Facciuta Lucana,
