Patterns of inheritance Artificial selection Patterns of inheritance

Learning outcomes (h)(i) the principles of artificial selection and its uses To include examples of selective breeding in plants and animals AND an appreciation of the importance of maintaining a resource of genetic material for use in selective breeding including wild types. (ii) the ethical considerations surrounding the use of artificial selection. To include a consideration of the more extreme examples of the use of artificial selection to ‘improve’ domestic species e.g. dog breeds.

Task What is artificial selection? Give examples. What is inbreeding depression? What is hybrid vigour? What are gene banks and how are they beneficial? What are the ethical considerations of artificial selection?
