Everyone should be going insane in the lab this week, scoring many hundreds of flies. That will be completed this week, and next week we'll be working on analysis of the data.

In class, we're finishing up chapter 5, and will begin chapter 8, on chromosomal mutations.

Problems: Chapter 8, 1-5, 9, 10, 13-15, 17, 23, 31 (these problems are identical in the 7th and 8th editions)
