"This resource had a fun lighthearted way for students to move on from monohybrid crosses to more complex forms of genetics. "

"This was a great review activity for genetics. I have used it for middle school and my HS biology students. It is a good break from pencil/paper work but also keeps students actively learning. "
star

Description

In this lab, students investigate how a combination of genes work together to create an organism. This activity helps to reinforce basic patterns of inheritance: dominant/recessive, incomplete dominance, codominance, and sex-linked traits.

Students will flip a coin to determine the genotypes of Mr. & Mrs. Monster, and describe the phenotypes associated. They will then act as a genetic counselor to advise the Monsters on the most likely phenotypes of their potential offspring (Punnett square practice).

Great value
I used this for my 10th grade Biology class. The steps are very well laid out. I had not taught Codominance or incomplete as well beforehand so I had to make some adjustments on the genomes. But other than that it well really well! We have block scheduling and I had the students also draw their monsters so it took the entire 90 minutes so keep that in mind when planning.
