The autosomal dominant trait may en defined as the trait that can express itself even in the heterozygous condition and in the homozygous dominant condition as well.

Mrs. Jones blood typing results showed agglutination with the plasma containing anti - B antibodies only. What is her blood type
MakcuM [25]

Answer:

Mrs Jones Blood type= B type.

Safe transfusion from: B and O blood type.

Explanation:

In the given example, the anti-B antibodies are present in the donor plasma.  Since anti-B antibodies react with B antigen present on the RBCs of blood, Mrs. Jones should have B antigen on the surface of her RBCs. The blood type with only B-antigen on the RBC's surface is blood type "B".  

Hence, her blood type is "B" type which has B antigens that react with anti B antibodies of the donor plasma causing agglutination and hemolysis of RBCs.  

She can get the blood of B and O blood types. Blood type O is a universal blood type as it does not have B or A antigens on the surface of its RBCs to initiate the agglutination.
