Gerry’s Gene Scene – Chromosome Mapping

This is the fifth in my series of ‘genetics explainer’ videos on YouTube for students, parents and teachers. I have received feedback from teachers that these videos are of great use in a flipped-classroom instructional strategy.

Mendelian genetics is a type of inheritance first described by Gregor Mendel in the 1860s and rediscovered in the early 20th century. Thomas Hunt Morgan and his student Alfred Sturtevant are credited with coming up with the idea to use crossing over percentage to map chromosomes. In this video, we will look at why there are unpredicted phenotypic ratios and how that knowledge can be used to map chromosomes.
