A grinning green and blue cartoon monster with red eyes and purple horns stands in a science lab with glowing chemical formulas.

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 Procedure: 1. Flip a coin twice to determine the genotype for each trait and record it in the data table. Heads = allele 1, Tails = allele 2 (Example: if you flipped heads twice, your monster will have two copies of allele 1 for his genotype.) 2. Determine the phenotype resulting from the allele pair for each trait. 3. Repeat steps 1-2 for each trait and complete the female monster’s Table 1.
