A Spanish Merino sheep population is characterized, for the first time, according to its frequencies for a total of nine polymorphic loci: three blood group factor systems, A, B and C, and the following red cell or serum polymorphisms: haemoglobin (Hb), carbonic anhydrase (CA), 'X protein', transferrin (Tf), arylesterase (EsA) and albumin (Al). Another locus, amylase (Am), did not show polymorphism.
