Lecture, chapter 5 - Polygenic and multifactorial inheritance

We started covering quantitative genetics, the subfield of genetics that studies polygenic and multifactorial inheritance based on observations on phenotypic variation.

We discussed the principle of regression to the mean and how statistics is used as an important tool in quantitative genetics. We focused on concepts that are specific to quantitative genetics, such as phenotypic distribution and distribution of environments.

We mentioned features of the interaction of genes and environment as preparation to discuss the concept of heritability.
