Darwin was unable to explain how characteristics are transferred from generation to generation. The solution was found in Gregor Mendel’s experiments with the common pea plant. Finally, we examine dominant and recessive traits and what the Hardy-Weinberg law proves. (10 minutes)

The reshuffling of chromosomes during meiosis is shown to ...(more details)		VHS $49.95 DVD $49.95 DVD + 3-Year Streaming $74.93 3-Year Streaming $49.95
		The Population Picture Returning to the larger themes of organic evolution, we again use the Hardy-Weinberg model, focusing on how the equilibrium of a population may be disturbed. Stabilizing, directional, and disruptive evolutionary phenomena are examined and we touch on...(more details)		VHS $49.95 DVD $49.95 DVD + 3-Year Streaming $74.93 3-Year Streaming $49.95
		Mutation and All That Although the mechanism of meiosis constantly reshuffles the gene pool of a population, only mutation can account for the upward progression of a species. Examining the structure of DNA and the alteration of the genetic code, we learn why the relation...(more details)		VHS $49.95 DVD $49.95 DVD + 3-Year Streaming $74.93 3-Year Streaming $49.95
