Abstract
In this paper, the polymorphisms from 6 microsatellites were used to assess genetic diversity and relationships in 5 sheep breeds from Albania and Kosovo. A total of 150 unrelated healthy individuals were selected, from different flocks. Allele diversity, observed heterozygosities, expected heterozygosities, F-statistics, G estimates, number of migrants per generation (Nm), and Nei’s DA distance were calculated. The sheep breeds display a high level of genetic variation as estimated by allelic diversity and heterozygosity. The overall observed and expected heterosygosity were 0.738 and 0.867, respectively. Inbreeding for all population is FIS = 0.035. The mean genetic differentiation, FST was 0.138. The analysis of molecular variance indicated that 13.89% of variance can be explained by differences among populations. Factorial Correspondent Analysis distinguishes 2 groups. These data were consistent with those obtained from mtDNA. Microsatellite polymorphism data were shown to be useful for estimating the genetic relationships between local sheep breeds from Albania and Kosovo.
Key words: Genetic distance, genetic diversity, local breeds, microsatellite, mtDNA sheep
