Students describe the differences between incomplete dominance and codominant alleles, and between multiple alleles and polygenic inheritance. They describe how internal and external environments affect gene expression. They then interpret testcrosses and pedigrees charts.
This PowerPoint jumps right into the details of unusual traits and how they are coded. The epistasis patterns in Labradors are used as a main example, and many instances of polygenic inheritance malfunctions are explained. All of this should grab your students' attention!
A survey of Mendelian genetics is presented through this handout. Biology prodigies answer questions about the Law of Segregation, phenotypic ratios, and dominance. They define genetics vocabulary terms and describe various genetic disorders. Not innovative, but very practical, this activity is a good review of genetics concepts.
Although these slides seem full of text, the information is bulleted and clear. There is a list of vocabulary and then two slides to define examples of Mendelian inheritance and rules of probability. The remaining five slides look at specific trends in inheritance and phenotype occurrence, with realistic examples to help your students' understanding.
In this worksheet, students will answer 4 fill in the blank statements about Mendelian inheritance and meiosis. Then students will use Punnett squares to answer three short answer questions. Students will match 8 genetics vocabulary words to their definitions. Finally, students will fill in 3 short answer questions on gene therapy and cloning.
