To develop a basic understanding of genetic principles and their application in biology.
To give an introduction to the concepts and principles of inheritance of genetic characters, their recombination and linkages.
To give a basic understanding of the genetic code and the replication of DNA.
To outline how genes are expressed into proteins, via transcription and translation.
To review the methods used to study the genetic material and how these methods are used in different applications.
To review the evidence for evolution from the fossil record, earth history, and comparisons of living organisms in terms of structure, function and genetic constitution.
To outline mechanisms for evolution, especially in terms of artificial and natural selection and genetic drift.
To explore the observational and experimental evidence for the role of these mechanisms in causing evolution.
This module provides the basis for other modules.

Teaching Rationale And Relationship
The lectures introduce the vocabulary of genetics and describe the principles and practices involved in cytogenetics, transmission genetics, molecular genetics and explain the key mechanisms of evolution and how to study them. The workshop sessions encourages students to apply their knowledge of transmission genetics in solving genetics problems and understanding the basic mechanisms of evolution. Students are encouraged to use the Life website to benefit from the support material provided including tests and animated tutorials. Students are steered towards readings centred on and around the Life textbook (Purves et al.). The practical sessions will help students to understand the concepts, techniques and methods of molecular genetics in greater detail and learn how to implement some of them by allowing them to complete practical tasks and watch demonstrations; the evolution lab which uses the museum resources aims at demonstrating the results of key evolutionary processes.
The format of resits will be determined by the Board of Examiners

Assessment Rationale And Relationship
The formative workshop exercise gives students a chance to test their problem solving skills during the semester. The examination and computer tests (both formative and summative) test the knowledge and understanding of information delivered in the lectures, workshop and practicals. The lab report assesses the skills of data collection, analysis and reporting.
