Following the fourth activity, it would be nice to invite a genetic counselor to class. He/she could explain their role in the field of genetics and answer students' questions about the "child" they created. The students could act as the parents in a counseling session, asking the counselor the questions they came up with during the activity.
These activities lead nicely into a study of family pedigrees. The students could use the traits from Table 1 in Activity One, check their own family members for each trait, and then determine each person's genotype by using the relationships between generations.
These activities could also lead to a study of probability. Students could use their own genotypes from Activity One in a Punnett square with their "spouse." They could then predict the chance of their producing a child with a particular genotype and phenotype.
The genetic disorders that were added in Activity One (such as Cystic Fibrosis and Muscular Dystrophy) lend themselves nicely to an activity in which the students look for the gene/protein relationship and how a mutated gene can lead to an altered protein, which may be the cause of the genetic disorder.
