This is a fast-paced lesson which goes through the main steps of selective breeding and looks at the potential risks of this process. The lesson begins by looking at the characteristics of a number of organisms that would be selected. Time is taken to ensure that students understand that selective breeding is not a new thing and has been going on for a very long time and therefore some of the problems associated with this are now being experienced. The actual process is reduced down into 5 steps which can be recalled and applied to questions. The remainder of the lesson looks at the potential issues with selective breeding. The reduction in the nose size of pugs is explored as an example of the health problems which bred animals may face.
This lesson has been written for GCSE students.
