The words "create a baby" will grab the attention of any student. After studying the probabilities for genotype and phenotype using Punnett squares, this is an activity that will unify all previous tasks. The activity asks students to illustrate a baby using prior knowledge of vocabulary such as allele, trait, phenotype, genotype, dominant, and recessive.
The goal of this lesson is to take the pieces and parts of the "genetic language" that has been taught using Punnett Squares and pull everything together to show that "genetic material from mom and dad make me." The creation of a baby from single inheritance traits will reinforce why we study probability of what offspring will look like, what an allele is, and what the difference between phenotype and genotype are.
Note that incomplete dominance and polygenic traits are represented by single gene traits only for the purposes of this lesson.
