BIO L320 – GENETICS LAB
Dr. Jacqueline Jones
Laboratory 7 – Blood Typing ABO
In this lab we will look at the ABO blood groups. You will perform standard tests to
identify blood types. You will also learn the importance of blood type identification and its uses
as well as the form and function of blood components.
To carry out this lab you MUST read the instructions very carefully and record your results in
the data table on the provided sheet. This is located in the lab 7 folder on Blackboard. Briefly,
you will be given four different samples of synthetic blood. You must determine the blood type
using the materials provided (anti-serum for each blood type). For additional information
regarding blood types and agglutination, please refer to PowerPoint slides posted on Blackboard.
This lab must be written in a lab report format, which includes the following; cover page,
introduction, materials and methods, results and discussion. You must include at least 2
references and they must be cited in the text. If you need assistant please refer to the website I
provided earlier in the semester, www.citefast.com. Make sure you use APA format. The data
table can be attached to the lab report. However, you are still required to discuss your data.
Lab worth: 50 points.
Pages needed from lab book: N/A Just print off instructions and the Lab 7 sheet posted
in Blackboard.

Codominance
An allelic relationship in which the
phenotype of both alleles are expressed in
a heterozygote
Comparing Codominance
ABO blood group and
Codominance
•
•
•
•
•
Human blood type is
determined by codominant alleles.
There are 3 alleles involved
in the human ABO Blood
group.
They are written as IA, IB, i
IA, IB are codominant. i is
recessive
These 3 alleles can result in
4 phenotypes
Red Blood
Cell Antigen
Genetically determined surface
proteins found on the red blood
cells
Red blood Cell Antibodies
•
•
•
Antibody: protein made by your body
Antibodies usually bind to foreign substances, such as bacteria and viruses,
and destroy them.
A red blood cell antibody is one that “attacks” red blood cells. Your red blood
cells have certain “markers” on them, called antigens. If your immune
system sees a red blood cell antigen that is “foreign” (such as from a blood
transfusion), it will make antibodies to destroy it.
Agglutination
Action of antibody crosslinking with antigens to produce visible clumps which
ultimately results into an auto immune reaction resulting in hemolysis
Rh Blood Group
•
•
•
•
Rh blood grouping is decided on
the basis of Rh factor.
It is the presence of an antigen D.
The alleles representing antigen
D can be written as D (dominant
Rh) and d (recessive Rh).
It is either present or absent on
the red blood cells. If present, you
are a positive blood type and if
absent, you are a negative blood
type.
