Genetic diversity and subdivision of 57 European and Middle-Eastern sheep breeds.
The population structure and genetic diversity of 57 European and Middle Eastern marginal and cosmopolitan sheep breeds from 15 countries were analysed by typing 31 microsatellite markers. Mean unbiased expected heterozygosities ranged from 0.63 in British Exmoor Horn to 0.77 in Albanian Ruda. South-eastern European and Middle-Eastern sheep breeds were significantly more variable than northwest...
متن کاملNorth European short-tailed breeds of sheep: a review.
The short-tailed sheep, native of an area stretching from Russia to Iceland, are generally considered a primitive type. These robust northern sheep seem to have been spread by Norse vikings to several countries in this area from the late eighth century to the middle of the eleventh century ad. They have several common characteristics in addition to the fluke-shaped and tapered short tail, such ...
متن کاملGenetic Diversity among European Cattle Breeds
Over the centuries since mankind first started farming, genetic variation has allowed the selection of the improved crops and livestock that have fed an ever increasing population. Maintaining genetic variation is crucial if we want to continue to improve our livestock and respond to changes in climate, disease or consumer preferences. This article describes work at the Roslin Institute on the ...
متن کاملA Genome Wide Survey of SNP Variation Reveals the Genetic Structure of Sheep Breeds
The genetic structure of sheep reflects their domestication and subsequent formation into discrete breeds. Understanding genetic structure is essential for achieving genetic improvement through genome-wide association studies, genomic selection and the dissection of quantitative traits. After identifying the first genome-wide set of SNP for sheep, we report on levels of genetic variability both...
متن کاملGenetic Characterization of Albanian Sheep Breeds by Microsatellite Markers
Albania is a Mediterranean country, located in West of Balkan Peninsula. Albanian farmers have a long tradition in sheep breeding. Sheep comprise one of the most important domestic livestock species in Albania and play an important role in the livelihood of local community since they are a good source of meat, milk and coarse wool (Dobi et al., 2006; Porcu and Markovic, 2005). There are three i...
