Biochemical and genetic studies on rabbit hemoglobin. I. Electrophoretic polymorphism of the beta chain

A genetic polymorphism of beta-chain rabbit (Oryctolagus cuniculus) hemoglobin is demonstrated by means of acid starch gel electrophoresis. The biochemical evidence presented suggests that a previously reported substitution of a neutral amino acid for a histidine is responsible for the detected genetic variation. Segregation analysis was performed in a sample of 15 matings with 49 offspring and confirmed the genetic hypothesis: two common alleles at an autosomal locus. The calculated gene frequencies in a random sample of 125 individuals are HBB*1 = 0.48 and HBB*2 = 0.52.
