Chapter 14 Mendel and the Gene Idea Overview: Drawing from the Deck of Genes What genetic principles account for the transmission of traits from parents to offspring? One possible explanation of heredity is a ?blending? hypothesis The idea that genetic material contributed by two parents mixes in a manner analogous to the way blue and yellow paints blend to make green An alternative to the blending model is the ?particulate? hypothesis of inheritance: the gene idea Parents pass on discrete heritable units, genes Gregor Mendel Documented a particulate mechanism of inheritance through his experiments with garden peas Figure 14.1 Concept 14.1: Mendel used the scientific approach to identify two laws of inheritance Mendel discovered the basic principles of heredity
