• By means of electrophoresis, sera of domestic fowls, guinea fowls and their hybrids were fractionized. And their immunoelectrophoretic patterns were used as the standard criteria for the interspecific comparisons. The authors were able to confirm the following results, and they presented some genetic considerations.1. The concentration of serum proteins of 53.5±6.4mg/ml was estimated in domestic fowls and also that of 37.0±1.4mg/ml was estimated in guinea fowls.2. Serum of domestic fowls was separated into 12 fractions. Excepting the fractions in α-region and γ-region, the other fractions in domestic fowl serum were in common with those in guinea fowl serum. And the components which exhibited the uncommon characteristics in α-region and γ-region were identified as α1-lipoprotein and immunoglobulin-G (IgG) respectively.3. The species difference in albumin is due to the difference of electrophoretic migrating rate of this component, i.e., the rate in domestic fowls surpassed that in guinea fowls.4. Two precipitin lines of albumin were observed in electrophoretic pattern of serum of the genus hybrids. Among them, the line migrated with a surpassing rate corresponds to the albumin in domestic fowls, and the other line migrated with an inferior rate corresponds to that in guinea fowls. And the authors assumed that these three albumin phenotypes are controlled by a pair of codominant allele.5. The precipitin line of α1-lipoprotein in domestic fowls was observed as a single line, while that in guinea fowls was observed as a compound line. And that in the hybrids was a single line and rather the same as that in domestic fowls. The authors assumed that this interspecific difference is due to the difference of the antigenic construction of α1-lipoprotein.6. The precipitin line of IgG showed a remarkable specific difference between two species concerned. And in their hybrids, the precipitation of IgG exihibited an intermediate characteristics. The authors consider that the interspecific difference of IgG is also due to the difference of the antigenic construction of this component.
