Summary A pair of sheep twins each had two populations of red cells. Population 1 was positive for antigens Aa, Ma and Mb, was low‐potassium type, possessed an amino acid transport system and was lysine‐negative phenotype. Population 2 was negative for antigens Aa, and Mb, was high‐potassium type, lacked the amino acid transport system and was lysine‐positive phenotype. Population 2 disappeared from both sheep over a period of 8 years.
