More population genetics of polyploidy!
I did a literature search today and found several interesting papers. I picked two for next week, but in the interest of time, I think we should focus on the first one (Walsh paper). The Comai paper can be background reading for people who want to do a little polyploidy catch-up (like me). Both Genetica and Nature Reviews Genetics are available online through the library.
Walsh, B. 2003. Population-genetic models of the fates of duplicate genes. Genetica 118: 279-294. I read the beginning of this paper and scanned the rest. It addresses some of the ideas we touched on at the end of the April 10th class. It gets real mathy at the end, but it seems like a well-written paper (aka focus on the text and slide over the math parts).
Comai, L. 2005. The advantages and disadvantages of being polyploid. Nature Reviews Genetics 6(11): 836-846. Nice review, lots of pretty pictures of difficult to visualize inheritance mechanisms. Introduces some molecular genetic concepts not covered in other two papers.
