Paul Andersen explains aspects of genetics that were not covered by Gregor Mendel. He begins with the following topics; incomplete dominance, codominance, epistasis, multiple alleles, and multiple genes. He then explains how linked genes were discovered by Thomas Hunt Morgan and Alfred Sturtevant. He also discusses sex-linked traits.

Paul Andersen explains the current classification system that we use in Biology. He starts with a brief history of taxonomy. He explains how the goal of classification is to reflect evolutionary relationships. He then explains how each individual organism is classified according to genus and species.
Paul Andersen explains the concept of coevolution. He begins with an analogy …
Paul Andersen explains the concept of coevolution. He begins with an analogy comparing the relationship of humans to technology with those of coevolving species. He then discriminates between coevolution and convergent evolution. He finishes by describing many symbiotic relationships that formed through coevolution.
