(*)The aim of this course is to introduce students to different concepts in genetics and evolution applicable to understanding trends in genomic data. Specifically, the course will concentrate on central concepts in population genetics describing the main evolutionary processes changing our genome. The main topics that will be covered are the basic laws of allelic distribution, the processes that change allele frequencies, with special emphasis on mutation and recombination, and the mechanisms of extinction and speciation. The course will be supported by exercises, which are an essential tool to understand the discussed concepts.
Goals
- To provide an introduction to genetics and evolution
- Explain relevant processes in genetics and evolution
- Apply concepts to solve basic exercises
- Learn to information related to evolutionary genetics to understand data structure

2 89-80;
3 70-79;
4 60-69;
5 0-59
Attendance: No attendance required for the lectures.
Student resources: I will be recording the sessions so you can listen to the lectures and presentations again.

(*)Lectures will be combined with exercises explained in class. Exercises will be solved outside of class, but some example questions will be explained on the blackboard. An important aim of the course is also for students to understand how experiments are performed to discover the evolutionary processes in our genome; thus, the course will also discuss methods and techniques to gather data which is analyzed by bioinformaticians.
