PPT-Ch 14 Human Inheritance

Human inheritance involves more issues than pea plants Relatively few traits follow a Mendelian inheritance pattern but we cannot ethically perform test crosses Most human traits are polygenic. 1.

The Different Forms of Inheritance. Mendel’s Inheritance (Monohybrid + . Dihybrid. ) = Last lesson. Incomplete dominance = This lesson. Codominance. = This lesson. These are some of the common dominant and recessive traits in humans that can be easily observed in people around you. . You . have two genes for them. One inherited from your father and one from your mother. The way that a physical trait is expressed, and hence the way you look is a result of either a combination of dominant genes, a dominant and a recessive gene or two recessive genes..
