SCALI, Monica et al. Genetic differentiation between Cinta Senese and commercial pig breeds using microsatellite. Electron. J. Biotechnol. [online]. 2012, vol.15, n.2, pp. 1-1. ISSN 0717-3458.

Background: Cinta Senese (CS) is an autochthonous Tuscan breed, which risked extinction since the ‘60s. Results: Monitoring the genetic variability of the actual population by use of DNA molecular markers is essential to address a correct breeding policy, finalized to obtain the race preservation and its fitness in the future. 17 SSRs autosomal markers and 1 associated to the X chromosome were used to genotype 86 individuals belonging to the CS and 12 belonging to two main white races Landrace (L), Large White (LW) and crosses between LW and L and L and CS widespread in Tuscany and used in the recent past to obtain hybrids with the CS. Conclusions: A dendrogram of similarity measures the relative genetic distance between individuals in the population. Data show that CS pigs have a distinct genotype from L, LW, LW x L and L x CS.
