Today we finished covering chapter 5, on polygenic inheritance.

We discussed concepts like distribution of environmental factors, norm of reaction, and heritability. We also discussed the importance of twin studies in complex traits research, and talked about a couple of examples of polygenic traits in humans: skin color and intelligence.

Tomorrow: Chapter 6, on cytogenetics.
