Microscopes and mutants

Description

As the 19th century gave way to the 20th, genetics came into its own as a science. This intro-level program shows how the development of the microscope pushed genetic studies forward, and includes in-depth discussion of early cell theory, particularly the first observations of meiosis and mitosis. Exploring Thomas Morgan Hunt's findings involving Drosophila mutation, the program covers sex-linked inheritance, the discovery of the X and Y chromosomes in the early 1900s, chromosomal roles in the transmission of genetic material, the importance of gene-mapping, and ways in which the science of genetics has been co-opted, particularly in the dead-end study of eugenics.
