Genetics: Heredity and Variation

Classical Genetics = Based solely on visible results of reproductive acts Molecular Genetics = Studies the structure and function of genes at a molecular level

Heredity = Transmission of traits from one generation to another Variation = Any difference existing between individuals of the same species

Classical Genetics = Concerned with genes, mutation, and phenotypes Molecular Genetics = Employs methods of both molecular biology and genetics

<p>Theory of Homunculus = Enlightenment-era theory where a fully formed individual exists within a germ cell prior to fertilization Theory of Epigenesis = Concept that structures develop during embryo development that are not pre-formed Blending Theory = Obsolete theory stating progeny inherit characteristics as an average of parent values Gene Theory = Principle that traits are passed from parents to offspring through gene transmission</p> Signup and view all the answers
