| Title : | GENETIC STRUCTURE OF THREE ALBANIAN LOCAL GOAT BREEDS BASED ON MICOSATELLITE MARKERS |
| Abstract : | Goats are an important livestock species in the hilly and mountainous area of Albania. The aim of the study was to estimate the genetic diversity of three local goat breeds in Albania by the use of 10 microsatellite markers. A total of 90 animals were selected as representative of three local goat breeds Velipoja, Dragobia and Smokthina. The molecular data were analyzed by different bioinformatics tools to estimate the genetic structure and genetic distances between the selected breeds. A total of 78 alleles were identified for 10 microsatellite loci. The number of alleles ranged from 4 (MAF209) to 11 (MAF70 and SRCRP5). The mean observed and expected heterozygosity values across all polymorphic loci in all populations were 0.573 and 0.67, respectively. The overall value for the polymorphic information content of all microsatellite loci was 0.637, indicating their suitability for genetic diversity analysis. The populations displayed heterozygosity deficit indicating the presence of inbreeding (FIS=0.143). Global breed differentiation (FST) was 0.018, indicating a very poor genetic differentiation. The Factorial Component Analysis (FCA) and Bayesian based clustering structure analysis indicated the admixture between breeds. AMOVA indicated that only 1.89% of the variation can be explained by the differences between breeds. All breeds display a high genetic diversity, but the differentiation between them is very poor. The high level of inbreeding and admixture between breeds can be explained with the breeding practices, with the small population size and Whalund effect |
