Genetic 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 کاملConservation priorities of genetic diversity in domesticated metapopulations: a study in taurine cattle breeds
We estimated neutral diversity of 21 European cattle breeds with 105 microsatellites. Nine of them resembled unselected Balkan Buša strains with diffuse breeding barriers and the 12 others were strongly differentiated, isolated breeds. Because of the impact of neutral genetic diversity on long-term population adaptive capacity, we discuss the long-term outcome of different conservation prioriti...
متن کاملGenetic diversity and relationships of endangered Spanish cattle breeds.
Information on the genetic structure and variability of autochthonous livestock breeds is essential for effective conservation programs. Here we present a molecular characterization on the basis of 30 microsatellite markers of 5 Spanish endangered cattle breeds Betizu (BET), Mallorquina (MAL), Menorquina, Monchina (MON), and Serrana de Teruel (ST) and of 2 fighting bull populations, Casta Navar...
متن کاملGenetic Diversity of Four Cattle Breeds Using Microsatellite Markers
Four cattle breeds (Gyr, Nellore, Guzerat and Holstein) were analyzed by amplification of genomic DNA using microsatellite loci to evaluate the genetic diversity within and among them. DNA samples of 18 animals from each breed were collected to access the genetic content of them. Allele frequencies were calculated and used to generate a Nei’s genetic distance matrix what was used to build a den...
متن کاملGenetic diversity and phylogenetic relationships in local cattle breeds of Senegal based on autosomal microsatellite markers
AIM In Senegal, uncontrolled cross-breeding of cattle breeds and changes in production systems are assumed to lead to an increase of gene flow between populations. This might constitute a relevant threat to livestock improvement. Therewith, this study was carried out to assess the current genetic diversity and the phylogenetic relationships of the four native Senegalese cattle breeds (Gobra zeb...
