Comparative aspects of biochemical polymorphism in the blood of Caprinae species and their hybrids

Abstract

Biochemical variation at 14 blood loci was reviewed, and specific features compared experimentally in sheep Ovis aries, mouflon Ovis mwimon, goat Capra hircus, aoudad Ammotragus lervia 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 H b ,&I and H b BB 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 , 8 chain genes. In general aoudad showed a closer affinity to goats than to sheep.

Genetic Structure and Variation of Van Cats

“…Genetic variation studies have been conducted concerning ME in domestic animals. In the studies performed on sheep (Tucker and Clarke 1980;Yaman and Tucker 1981), S, F, and FS bands were observed, as was the case in the present study of cat breeds. In a study performed on the goats of Argentina (Deza et al 2000), A, AB, and B bands (similar to those bands observed in cats) were observed.…”

Relationships between rare breeds of sheep in the Netherlands as based on blood‐typing

“…The samples were despatched by air to England and were tested as soon as possible after arrival. The tests comprised identification of red cell antigens and of red cell and plasma protein and enzyme variants (Tucker, 1971(Tucker, ,1975(Tucker, , 1976Tucker & Clarke, 1980). Red cell antigen factors controlled by the A, B, C, D , M , and R-Z loci were examined with 16 different reagents.…”

Genetic markers in the blood of Spanish goat breeds

“…When goat red cell lysates are subjected to electrophoresis and stained with a protein stain, the more anodal visible zone has been given the designation of 'X' protein (Tucker & Clarke, 1980). Two different phenotypes of 'X' protein have been described in goats by these authors.…”

“…We have also detected two different 'X' protein phenotypes. One of them, perhaps equivalent to the three-banded one described by Tucker & Clarke (1980), consists of one major and two minor bands and has been designated X+ protein.…”
