It took me longer than it should have, but I finally added a link to the app I used in Tuesday’s lecture to illustrate partitioning of the genetic variance into additive and dominance components. You’ll find the link below and in the lecture detail page for Tuesday and for Thursday. In the lecture detail page for Thursday you’ll also find a link to an app illustrating the resemblance between parents and offspring. As noted there, I discovered that there’s a problem in simulations involving non-additive allelic effects. I plan to investigate and fix the problem over Thanksgiving break. I’ll post a note here when I’ve fixed it.
