Summary

A rather common haemoglobin variant was detected in the Sardinian and Altamurana sheep breeds. The mutated globin chain appears to be produced under the control of an allele at the HBB locus and due to a neutral amino acid substitution. The variant will be provisionally referred to as the Hb I.
