Your blood type is established before you are
born, by specific genes inherited from your
parents.
These two genes - one gene from your mother
and one from your father - determine your
blood type by causing proteins called
agglutinogens to exist on the surface of all of
your red blood cells.
There are 3 alleles or genes for blood type:
A, B, & O. Since we have 2 genes, there are 6
possible combinations: AA, AO, BB, BO,
AB, and OO.
Give the genotype(s) for each blood type.
Type A = ____ ____ Type AB = ____
Type B = ____ ____ Type O = ____
Genetics of Blood

blood; they are produced in the bone marrow and contain a protein
called hemoglobin that carries oxygen to our cells.

system and destroy infectious agents called pathogens.
PLASMA – This is the yellowish liquid portion of blood that contains
electrolytes, nutrients and vitamins, hormones, clotting factors, and
proteins such as antibodies to fight infection.
PLATELETS (Thrombocytes) – The clotting factors that are carried in
the plasma; they clot together in a process called coagulation to seal a
wound and prevent a loss of blood.

People with Type O blood are called universal
donors, because they can give blood to any
blood type. People with Type AB blood are
called universal recipients, because they can
receive any blood type.

A small pool of blood and a weapon was found near a garbage dumpster. After examining the area, the CSI on the scene discovered a body in the garbage dumpster and identified him as Earnest “One-Eyed” Earl. Earl had a wound to his chest that will be analyzed by the medical examiner.
The CSI tested blood samples from the blood poolscene. It was determined that it was human blood, but he needs to know the blood type to help identify if it was from the victim or the person who murdered him. He has identified three suspects that either knew the victim or were seen in the area before the body was discovered. He would like to question them further while he waits for DNA test results.
