Serum transferrins in Merino sheep

Abstract
Serum samples from 1963 Merino sheep were examined for serum transferrin type. Two of the five transferrin alleles previously described in British breeds of sheep, viz.T fAandT fc, were found, butT fB,T fDandT fEwere absent. Evidence for seven further transferrin alleles was obtained. These alleles were codedT fF,T fG,T fH,T fJ,T fN,T fKandT fLin decreasing order of mobility of the zones they produce in starch gel.Gene frequency data is presented for the populations studied.
