Genetic Variability and Population Structure in the Sardinian Anglo-Arab Horse.

ABSTRACT: The Sardinian Anglo Arab (SAA) is a famous horse breed in Italy, with a significant historical background in the island of Sardinia. The aim of the study is to perform an evaluation of genetic variability in SAA using pedigree and mitochondrial data. In the current population, pedigree completeness was observed to be close to 100%, while the inbreeding coefficient and the average relatedness were lower than 3%. The ratio of effective founders/numbers of ancestors was 3.68 for the whole pedigree. The effective population size (N_e) computed by an individual increase in inbreeding (N_{e_1}) was 456.86, the N_e on equivalent generations (N_{e_2}) was 184.75, and this value slightly increased to 209.31 when computed by log-regression on equivalent generation
