With three endonucleases Bam HI Eco RI and Hind III Sardinian mouflons with Hb B Hb BM and Hb M show identical restriction patterns to sheep with Hb A Hb AB and Hb B respectively. Therefore in Sardinian mouflons as in domestic sheep the 3-globin gene cluster shows two haplotypes characterized by the triplication or duplication of an ancestral four gene set e-e-Tpfl-fl . domestic sheep Sardinian mouflon haemoglobin I fl-globin cluster Resume - Comparaison du groupe de genes de la globine- du mouton domestique Ovis aries et du mouflon de Sardaigne Ovis gmelini musimon .
