The Latxa and the Karrantzar sheep breeds from the Basque Autonomous Comunity are a particular example of livestock population raised by a traditional breeding system. We have investigated the distribution of a llele and genotype frequencies on a large number of herds applying classical electrophoretic methods for typing the HBB, DIA1, TFtpand ES loci. Moreover, we have set up new electrophoretic methods based on isoelectric focusing to extend this analysis to the ME1, Pi1, Pi2 and TFstp polymorphisms. Furthermore, we have analysed the diversity within and between different levels of population subdivisions by grouping the herds in types, varieties and breeds. Our results suggest that, contrary to what we coud have expected based on the morphological features of the animals, between the type Aizkorri of the Black Face variety and the White Face variety exists the closest genetic similarity, while the type Gorbea of Black Face differenciates from the other two. On the other hand, as we could expect, the Karrantzar breed shows the largest genetic differentiation.
