RESUMO

The knowledge of the existing genetic variability in local breeds of livestock is important for the conservation genetics and for programs of animal breeding. The general objective of this research was to analyze the diversity and the genetic variability of Brazilian Creole Wool Sheep raised in the Southearn region of the country through the utilization of molecular markers (RAPD and STR). The analyzed samples represented the conservation nucleus belonging to Brazilian Agricultural Research Corporation - EMBRAPA as well as others flocks present in the region. The results indicated that the total genetic variability of the Fronteira breed and the ecotype Serrana is not represented in the EMBRAPAs flock nor in the others sampled flocks. The animals kept by EMBRAPA presented a higher introgression of Corriedale than that of the external population. In all analyses the Zebua ecotype was the most dissimilar among the Creoles.
