Greg Chapman completed this course, spending 1 hours a week on it and found the course difficulty to be easy.
This is a good course as a broad introduction to topics in genetics. Dr. O'Brien's lectures were somewhat like you'd expect from an introductory science course, but Dr. St. Leger's lectures were more like what you might expect from a "science cafe" type of informal lecture. There's quite a bit of breadth in the topics covered (from behavior to biotechnology), but not a lot of depth; the course will whet your appetite to explore some of the topics in more detail. They do link to some resources for more exploration of the topics covered, but I wish they had linked to more academic resources as well. The quizzes are all recall based, so the course is not very rigorous, but it is interesting and engaging.
