Lecture, chapter 11 - Mutation

Today we started the chapter on mutation, the source of genetic variation.

Our focus in this chapter will be on how mutations are detected and how they happen.

We discussed traditional methods to pinpoint the individual in which a mutation that affects the phenotype appears. These methods apply to mutations that produce a dominant allele of a trait controlled by one fully penetrant and expressed gene.

We also discussed how mutation rate has been traditionally estimated in humans, and then we mentioned the factors that can affect the mutation rate across genes.


NOTE:

On Friday students are to bring a printout of a genetics-related news article (from a news paper, magazine, podcast, etc.) and be ready to discuss it with the instructor and classmates. Small discussion groups will meet and then the most relevant articles will be discussed in a general forum.

(if at least 17 different topics are submitted 5 bonus points will be awarded to all students who bring an article and are involved in the discussions)
