Students take on the role of a genetics counselor in this fun simulation. Each student is assigned a different couple that has come to them to find out more about the probability of having a child with a specific genetic disorder and to find out more about the genetic disorder. During the activity, students read the family history of the couple and use this to create a pedigree. From this pedigree, the students identify the genotype of the couple and then calculate the probability of having a child with the disorder.
Then the students research the disorder to find out the characteristics of the disorder. Finally, the students write a three paragraph business letter to the couple to describe their probability of having a child with the disability, the characteristics of the disorder, and his or her (the genetic counselor’s) recommendations.
