Name: Monster Genetics Lab
You have learned about many different patterns of inheritance. Some are simple dominant or recessive, as in
Mendelian traits. Some are more complex, such as incomplete dominant or codominant traits. In this lab you
will investigate how a combination of these genes works to create an organism.
Part 1: Mom
1. Flip a coin twice to determine the genotype for each trait and record it in the data table.
Heads = Dominant Trait
Tails = Recessive Trait
2. Determine the phenotype resulting from the allele pair for each trait.
