Give your biology students a focused look at genes and chromosomes with ninety questions built for real classroom use, whether you are starting a new unit or reviewing before a test.
Sample questions include "What does a punnett square illustrate?", "What determines the traits of an organism?", and "What can result from a deletion mutation?"
Each worksheet reviews the same core ideas from a different angle. Use them across a week or unit so students see the material three times without it ever feeling repetitive.
This set is part of a standards aligned biology unit. The unit also covers Proteins and Traits, Structural Gene Changes, Beneficial Mutations, Harmful Mutations, Neutral Mutations, and Modeling Gene Changes, all in the same three worksheet format, so your classroom routine stays familiar while the topic changes.
Suitable for Grade 7 biology classes, and for review at any point in the school year. This set is aligned to NGSS standard MS-LS3-1.
