Abstract

The evolutionary origin of murine line based on a phylogenetic tree made on sequence data of ∞- and β -hemoglobin chains, followed by the diversity spectrum of hemoglobin genes in two wild species of murine rodents: Rattus rattus rufescens (house rat) and Bandicota indica (bandicoot rat) has been reported. Each house rat contains six hemoglobin types involving two infinity-and three β-chains, which suggests a probable gene duplication at the oc chain locus and a gene triplication at the β-chain locus. Each bandicoot rat contains one infinity-and two β -chains suggesting a probable gene duplication at the β-chain locus. Peptide pattern analysis of the polypeptide chains of these murine hemoglobins further indicates that intraspecies differences among duplicated chains of the same kind are less than interspecies differences among corresponding ∞-and β -chains.
