ESTUDIO DE LA VARIABILIDAD GENÉTICA EN LA RAZA BOVINA MALLORQUINA PARA PROPÓSITOS DE CONSERVACIÓN Genetic Diversity Measures of Local Cattle Majorcan Breed for Conservation Purposes

摘要: According to the Food and Agriculture Organization of United Nations (FAO), animal genetic resources available throughout world are in dramatic state decline. This results disappearance substantial numbers local populations, consequent loss their ability adapt genetically environments. study analyzes variability structure a limited rare population, beef cattle breed from Majorca Isle (Spain): Mallorquina breed, based on analysis 15 microsatellites. A total 26 individuals, grouped according coat color, were sampled: 12 red variety 14 black variety. The relationships between these subpopulations five other Spanish breeds analyzed compared. levels very similar for two varieties, comparable those obtained Europeans breeds. value differentiation (FST) varieties was low (0.3%), indicating existence high gene flow groups, great similarity them. On hand, values FIS FIT 1.9% 1.6%, with no statistical difference zero, showing this Hardy Weinberg equilibrium. probability exclusion (PE) 99.9%, which allows us utilize markers as good tool individual identification parentage testing. Genetic distance dendrogram show clear separation peninsular bovine populations Majorcan
