Biochemical differentiation between the Wild rabbit (Oryctolagus cuniculus L.), the Domestic rabbit and the Brown hare (Lepus europaeus Pallas)

Twenty five specimens of the brown hare and fourteen specimens of the wild rabbit were examined for genetic differentiation and polymorphism in 28 enzyme systems by means of horizontal starch gel electrophoresis and isoelectric focusing in polyacrylamide gels. Indices of genetic variation show values similar to those averaged over numerous mammalian species. A D-value of 0, 0288 between wild and domestic rabbits suggests a high amount of gene frequency changes at enzyme loci during domestication. Evolutionary time of divergence between the rabbit and the hare (about 2430000 years) calculated from electrophoretic data is in good agreement with palaeontological findings.
