The Haemoglobins of a Sheep-Goat Hybrid Foetus and those of the Parent Species

Abstract

SummaryElectrophoretic examination of the haemoglobins of a sheep-goat hybrid foetus indicated the presence of haemoglobins found in the foetuses of the parent species only. No interaction products were found.In vitro "hybridization" experiments indicate that the difference in electrophoretic mobility between sheep A, sheep B, goat A, goat F, and sheep F haemoglobins is due to a difference in the non-ex-portion of the haemoglobin molecules. The absence of electrophoretically detectable haemoglobin interaction products in the hybrid foetus is explained by the finding that the ex-polypeptides of the parent species are electrophoretically indistinguishable.
