3.3 Variation of Traits

Students investigate the differences between inherited genetic traits and traits learned or influenced by the environment. They explore the phenomena that offspring may express different traits than parents as they learn about dominant and recessive genes and also investigate how predicted outcomes compare to experimental results. Angelina, Mylo, and Suzi introduce the design problem when challenged to examine different traits found in three sets of seeds. Students then model how the gene for stem color is passed on and expressed among sample sets.
