Blood Types Tutorial
Go to http://www.biology.arizona.edu/human_bio/problem_sets/blood_types/Intro.html and answer
the following questions:
1.
Human blood type is determined by ______________________________.
2.
An _______________________ is one of several different forms of genetic
information that is present in our DNA at a specific location on a specific
chromosome.
3. What are the 3 alleles for human blood type?
a.
b.
c.
4. A description of the pair of alleles in our DNA is called the ______________________________.

A __________________________________is used to determine whether the
A and/or B characteristics are present in a blood sample.
7.
It is not possible to determine the ____________________________________
from a blood test result of either
_______________________________________.
8.
If someone has blood type A, they must have at least one copy of the A allele,
but they could have two copies. Their genotype is either AA or AO. Similarly,
someone who is blood type B could have a genotype of either BB or BO.
Complete the chart:
Blood Type
A
Possible genotypes
B
9.
A blood test of either ________________________________________ is
more informative. Someone with blood type AB must have both
the___________________________________.
The_______________________________ must be AB. Someone with
_______________________________ has neither
the________________________________________. The genotype must be
______________. Complete the chart
Blood Type
AB
Possible genotypes
O
10.
Each biological parent donates ____________________ of their two ABO
alleles to their child. A mother who is ________________________ can only
pass an ___________________________________ to her son or daughter. A
father who is __________________________________could pass either
an_________________________________________________ to his son or
daughter. This couple could have children of either
__________________________________________ (O from mother and A
from father) or ________________________________ (O from mother and B
from father).
11.
Since there are _________ different maternal blood types and__________
different paternal blood types possible, there are ___________ different
combinations to consider when predicting the blood type of children.
12.
The _______________________________ genetic information is also
inherited from our parents, but it is inherited ___________________________
of the ABO blood type alleles. There are 2 different alleles for the Rh factor
known as ___________________________________________

Complete the problem set questions
1. Is a type O possible in this situation?
2. Possible blood types of offspring
3. What blood type would the father be?
4. What are the potential blood types of the father of my son?
5. Who is NOT the father of my grandson?
6. Do we all have the same biological father?
