SBI3U Genetics Unit Review - Chapters 3,4 and a bit of 5
Overall Unit Expectations covered by unit test:

Investigate genetic processes, including those that occur during meiosis, and analyse data to
solve basic genetics problems involving monohybrid and dihybrid crosses.

Demonstrate an understanding of concepts, processes, and technologies related to the
transmission of hereditary characteristics.
Main Concepts






Be able to compare/contrast the processes of mitosis and meiosis
Understand how genetic diversity is created during the process of meiosis
Explain dysfunctions that occur when mitosis and meiosis processes don’t work properly
Perform a test cross for traits that may be dominant, recessive, co-dominant, show incomplete
dominance, have multiple alleles or are sex-linked
Use a pedigree to predict the genotypes and phenotypes of family members who may carry,
be normal or have a particular trait or disease.
Understand the benefits and controversial ethics of new genetic technologies and testing
