This is an extension of the Human Traits survey activity designed to introduce students to genes, genotypes, and simple inheritance patterns. Using information from the Human Traits Survey, students make guesses about their own genotype, create gametes from their genotypes, then make “babies” with a partner. Along the way students discover answers to the questions: What are genes? How are genes (and traits) passed on? How are gametes different than other cells in our body? Why do I look like mom in some ways and dad in other ways and neither of them in still other ways? Why don’t siblings look alike?
Can explain the relationship between genotype and phenotype.
Can explain the inheritance of single gene traits using dominant/recessive relationships.
Can take genotype information from 2 parents, model the creation of gametes by independent assortment, and use those gametes to create offspring.
