Give your biology students a focused look at sources of genetic variation with ninety questions built for real classroom use, whether you are starting a new unit or reviewing before a test.
Sample questions include "Which mutation type can result from the insertion or deletion of nucleotides?", "What role do mutations play in evolution?", and "During which stage of meiosis does crossing over occur?"
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 complete NGSS aligned biology unit. The unit also covers Polygenic Traits and Phenotypes, Environmental Effects on Traits, Gene Expression and Regulation, Heritability and Genetics, Modern Genetics and Trait Analysis, and Pedigrees and Family Inheritance, all in the same three worksheet format, so your classroom routine stays familiar while the topic changes.
Suitable for Grade 9-12 biology classes, and for NGSS aligned review at any point in the school year. This set is aligned to NGSS standard HS-LS3-2.
