  • Title: Comparative aspects of biochemical polymorphism in the blood of Caprinae species and their hybrids.
    Author: Tucker EM, Clarke SW.
    Journal: Anim Blood Groups Biochem Genet; 1980; 11(3):163-83. PubMed ID: 7458003.
    Abstract:
    Biochemical variation at 14 blood loci was reviewed, and specific features compared experimentally in sheep Ovis aries, mouflon Ovis musimon, goat Capra hircus, aoudad Ammotragus Iervia and in 2 stillborn aoudad X goat hybrids. Variation at 3 loci was also studied in dall sheep Ovis dalli, bighorn sheep Ovis canadensis and rocky mountain goat Oreamnos americanus. Haemoglobin C production in an anaemic Hb AB mouflon and in mouflon X sheep hybrids was examined. Mouflon differ from domestic sheep in that synthesis of both Hb beta A and Hb beta B chains is switched off during Hb C production. The mouflon X sheep hybrids switched off one or both chains depending on whether they had inherited sheep or mouflon Hb beta chain genes. In general aoudad showed a closer affinity to goats than to sheep.
