4. So,
A is a classification of blood based on the
presence or absence of inherited antigenic substances on
the surface of red blood cells (RBCs).

6. Out of the following A & B are equally dominant while O is
recessive.
8. individuals have both A and B antigens on the
surface of their RBCs, and their blood plasma does not contain any
antibodies against either A or B antigen. Therefore, an individual with
type AB blood can receive blood from any group, but cannot donate
blood to any group other than AB. They are known as universal
recipients.
individuals have the A antigen on the surface of
their RBCs, and blood serum containing specific antibodies against
the B antigen. Therefore, a group A individual can receive blood only
from individuals of groups A or O, and can donate blood to
individuals with type A or AB.
9. individuals have the B antigen on the surface of
their RBCs, and blood serum containing specific antibodies against
the A antigen. Therefore, a group B individual can receive blood only
from individuals of groups B or O and can donate blood to individuals
with type B or AB.
individuals do not have either A or B antigens on
the surface of their RBCs, and their blood serum contains specific
anti-A and anti-B antibodies against the A and B blood group
antigens. Therefore, a group O individual can receive blood only from
a group O individual, but can donate blood to individuals of any ABO
blood group. They are known as universal donors.

11. • To check the ratio of different blood groups in people.
• To analyze the +/- blood group ratio in people.
• To find the majority and minority blood group.
18. • Majority Blood Group=B+(42)
• 2nd Majority Blood Group=O+(32)
• Minority Blood Groups
A-(1), AB-(1), B-(6), O-(2)
• Out of every 100 people, 90 are +Rh positive while the
remaining 10 are Rh negative.
• B+ and O+ blood group people constitute more than 50% of
the total.
• A+ and AB+ blood group people constitute about 30% of the
total.
