Hemoglobin Polymorphism and Morphometrical Correlates in the West African Dwarf Sheep of Nigeria

Red cells extracted from blood samples taken by jugular venipuncture from a total of thirty-six traditionally managed adult West African Dwarf rams and ewes were subjected to starch gel electrophoresis, stained to reveal the activities of different allelemorphs at hemoglobin locus and analyzed. The...
