Haemoglobin polymorphism in Norwegian red cattle.
By the use of isoelectric focusing in polyacrylamide gels and the Immobiline method at pH range 7.1-7.7, three haemoglobin (Hb) phenotypes were observed in Norwegian Red Cattle. Two one-band phenotypes named HbA4 and HbA6 occurred in unequal proportions in their two-band combination type with the cathodal HbA6 being the stronger. In 76 dam-offspring pairs the distribution of phenotypes were in agreement with codominant single gene inheritance. In an unselected material of 140 animals, gene frequencies were HbA4 = 0.94 and HbA6 = 0.06.
