Product Description
This activity can be used as a fun, formative assessment that the students really enjoy doing. Students are presented with the following scenario:

Imagine that you are a princess and it has been determined through genetic counseling that you are a carrier for the sex-linked trait of hemophilia. Hemophilia is a disorder where the blood does not clot properly. You are dating two princes from two different royal families and you are concerned about the possibility of your children having hemophilia. So, before you become serious about either relationship, you decide to do some research. You hope your research will help you decide which relationship might be the best for you to pursue.

Students will determine the answer to this problem by setting up Punnett squares and analyzing pedigrees. They should be familiar with the following concepts/terms before completing the assignment:

-sex-linked trait
-Punnett squares
-pedigrees
-normal/affected/carrier
-genotype
-phenotype

An answer key is included.
