1. Explain what is meant by the term agglutination.
2. What is the blood group of person X?
3. What is the blood group of person Y?
4. Explain why the blood from person X agglutinates

Answer 1

Answer:

All humans and many other primates can be typed for the ABO blood group. There are four principal types: A, B, AB, and O. There are two antigens and two antibodies that are mostly responsible for the ABO types. The specific combination of these four components determines an individual's type in most cases. The table below shows the possible permutations of antigens and antibodies with the corresponding ABO type ("yes" indicates the presence of a component and "no" indicates its absence in the blood of an individual).
