Abstract

The agglutinin having affinity for the sheep red cells was found in Tulip bulb extract. The sheep red cells agglutinated by this extract were T type and those not agglutinated were t type. The phenotype frequency of the T type was estimated to be 58.00% for Corriedale, 78.38% for Suffolk, 90.91% for Romney Marsh and 40.00% for Border Leicester, respectively. The genetic study on the T system proved that inheritance of this system was controlled by a dominant allele at an autosomal locus. The gene frequency of T was 0.3519 for Corriedale, 0.5350 for Suffolk, 0.6985 for Romney Marsh and 0.2254 for Border Leicester, respectively. The comparison test was made between the T system and other blood group systems already reported. The reaction pattern of the T system was different from the Sh1, D, R, 0, Aa, Ab, Ca, Ma, Mb and Mc sheep blood group systems.
