Reviewer Comments:

“Simple activity but efficient with a good assessment and likely good student interest.”

"The strength of this activity are the assessments. Students draw a fictitious chromosome which requires knowledge and creativity, because they must place their own ideas for traits on it. Then they must do a class presentations where they present one of the traits on their chromosome and how it is inherited."
