Genomic Tools for the Characterization of Local Animal Genetic Resources: Application in Mascaruna Goat.

ABSTRACT: Italy contains a large number of local goat populations, some of which do not have a recognized genetic structure. The "Mascaruna" is a goat population reared for milk production in Sicily. In this study, a total of 72 individuals were genotyped with the Illumina Goat_IGGC_65K_v2 BeadChip with the aim to characterize the genetic diversity, population structure and relatedness with another 31 Italian goat populations. The results displayed a moderate level of genetic variability for Mascaruna, in concordance with the estimated values for Italian goats. Runs of homozygosity islands are linked to genes involved in milk production, immune response and local adaptation. Population structure analyses separated Mascaruna from the other goat populations, indicating a clear genetic differentiation.
