Human Genetics & Evolution

BIOL31402 Human Genetics & Evolution 10 Semester 2 Undergraduate Level 3 Emma Jenkinson Unit coordinator Miriam Smith Unit coordinator 1 FHEQ level (Framework for Higher Education Qualifications) ' Last part of a Bachelors ' European Credit Transfer & Accumulation System Rating : 5.0 You will be able to explain how human populations evolved using evidence supported by the fossil record as well as advances in sequencing technologies. You will form an understanding of human genome sequence diversity, and how different types of pathological sequence variations cause genetic disease. Topics include: human evolution, population migrations, population sequence diversity, evolution of genetic disease, analysis of genetic disease in population-based research, diagnosis of genetic disease, molecular basis of genetic disease, personalised medicine. The balance of topics in this unit is approximately 1/3 evolution, 2/3 genetic disease.

The balance of topics in this unit is approximately 1/3 evolution, 2/3 genetic disease. The study of human genetic complexity and disease is a rapidly expanding field driven by advances in new technologies which facilitate large-scale projects to catalogue human genetic variation. These large-scale sequencing projects have revealed support for our understanding of human evolution and population migrations based on the fossil record.  These studies have also revealed the extent of human genome sequence variations.  However, understanding the link between genetic variation and the resulting phenotype presents challenges, as is apparent from large-scale association studies. This unit will explore how studying human genome sequences can inform our understanding of genetic disease and evolution.
